Adoption
Adoption is God's act of granting those in Christ the recognized standing, inheritance, and full rights of sons within His household.
Christ-centered biblical teaching for readers, teachers, and churches.
Many biblical and theological terms are used often but understood poorly. This glossary exists to define important words clearly, biblically, and usefully.
Adoption is God's act of granting those in Christ the recognized standing, inheritance, and full rights of sons within His household.
An apostle is one sent with delegated authority to represent and carry out the mission of the one who sent him. The word apostle means "sent one." Scripture uses the term in more than one sense, though always with the idea of authorized representation and mission.
The highest use of the term apostle is applied uniquely to Jesus Christ, who is called: "The Apostle and High Priest of our profession…" (Hebrews 3:1)
Christ is the One sent from the Father to reveal God perfectly and accomplish redemption. Every other form of apostolic ministry ultimately derives from Him.
Moses also stands as a lesser covenantal counterpart to Christ's apostolic office. As Moses was sent by God to establish and lead the old covenant people, Christ is the greater Apostle sent from the Father to establish the new covenant people of God.
The New Testament then speaks of the apostles of Christ, especially the Twelve together with Paul. These men were personally commissioned by the risen Christ as foundational witnesses of His resurrection.
Their role was unique and foundational. Paul describes the church as: "Built upon the foundation of the apostles and prophets, Jesus Christ himself being the chief corner stone." (Ephesians 2:20)
A foundation is laid once, not repeatedly. For this reason, the apostles of Christ should not be viewed as an endlessly repeatable office possessing ongoing revelatory authority equal to the New Testament apostles.
Are all apostles equal in Scripture?
No. Scripture uses the term in different senses. Christ uniquely stands as the Apostle sent from the Father, the apostles of Christ served as foundational witnesses of the resurrection, and churches may also send missionaries or representatives in a broader apostolic sense.
Are modern self-proclaimed apostles equal to the apostles of Christ?
No. The apostles of Christ held a unique foundational role as eyewitnesses commissioned directly by the risen Lord. Scripture presents the church as built upon the foundation of the apostles and prophets. Foundations are laid once, not repeatedly.
Does apostolic authority mean unlimited spiritual power?
No. Apostolic authority in Scripture is delegated, representative, and accountable to Christ. Apostles are servants sent to proclaim the gospel, not spiritual monarchs ruling by personal authority.
Christian ministry is fundamentally a stewardship rather than self-created authority. Those sent to serve Christ are called to humility, faithfulness, sacrifice, and obedience to the One who sends them.
The Ascension is the exaltation of the risen Christ to the right hand of the Father, where He intercedes for His people and from where He pours out the Holy Spirit upon the church until all things are placed beneath His feet.
After His resurrection, Jesus remained with His disciples for forty days, teaching them concerning the kingdom of God. He then ascended bodily into heaven before their eyes.
Acts records: "While they beheld, he was taken up; and a cloud received him out of their sight." (Acts 1:9)
The Ascension is not merely Christ's departure from earth. It is His exaltation to the Father's right hand, connected to His heavenly session, intercession, authority, and the outpouring of the Holy Spirit.
Peter explains Pentecost in exactly these terms: "Therefore being by the right hand of God exalted, and having received of the Father the promise of the Holy Ghost, he hath shed forth this…" (Acts 2:33)
The Spirit is poured out because the Son has ascended. The Ascension therefore stands as the great hinge between the resurrection and Pentecost.
The New Testament repeatedly connects Christ's Ascension with Psalm 110: "Sit thou at my right hand, until I make thine enemies thy footstool." Christ now sits at the Father's right hand as the exalted Son and heavenly High Priest, interceding for His people while awaiting the final subjection of all things beneath Him.
Did Jesus stop working after the Ascension?
No. Scripture presents Christ actively interceding for His people, guiding His church, and pouring out the Spirit from the Father's right hand.
Does the Ascension mean Christ's kingdom is already fully consummated?
No. Christ is exalted at the Father's right hand, but Scripture still anticipates the future visible subjection of all enemies beneath Him.
Why is the Ascension important to Pentecost?
Pentecost flows from Christ's exaltation. Peter explicitly teaches that the ascended Christ poured out the Holy Spirit upon the church.
The church does not labor alone in the world. The risen Christ intercedes for His people, sustains His church, and will one day return openly in glory. Christians therefore live not in despair or triumphalism, but in faithful hope beneath the exalted Christ.
Assurance is the settled confidence that one belongs to God through faith in Jesus Christ and the continuing work of the Holy Spirit.
Atonement is the saving work of Jesus Christ by which sin is dealt with, justice is satisfied, and reconciliation with God is made possible.
Baptism is the Gospel sign by which a believer publicly identifies with the death, burial, and resurrection of Jesus Christ.
The baptism of the Spirit is the once-for-all covenantal outpouring of the Holy Spirit by the exalted Christ, through which the people of God were immersed into one Spirit-formed body across Pentecost, Samaria, and the inclusion of the Gentiles.
John the Baptist first announced the coming baptism of the Spirit when he declared concerning Jesus: "He shall baptize you with the Holy Ghost…" (Mark 1:8)
The baptism of the Spirit is therefore fundamentally Christ's work. The risen and exalted Son pours out the Spirit upon His people.
This promise reaches its visible beginning at Pentecost in Acts 2. The disciples were gathered together when suddenly the sound of a rushing mighty wind filled the house, tongues of fire appeared, and the gathered assembly was filled with the Holy Spirit.
The imagery is immersive. The people are surrounded, filled, and overwhelmed by the presence of the Spirit poured out from the exalted Christ.
Pentecost should therefore be understood not merely as an individual spiritual experience, but as the beginning of a covenantal incorporation event through which Christ forms His church.
This event unfolds progressively through Acts. In Acts 8, the Samaritans publicly receive the Spirit in the presence of Peter and John. In Acts 10, the Spirit falls upon the Gentiles in the house of Cornelius while Peter proclaims Christ.
These events are not best understood as disconnected baptisms or separate churches. Rather, they form the progressive completion of one Spirit-baptism event publicly incorporating Jews, Samaritans, and Gentiles into one covenant people.
Peter's presence at all three moments is therefore deeply significant. The kingdom is being opened visibly to all peoples through one gospel, one Spirit, and one church.
Paul later explains the theological meaning of this reality: "For by one Spirit are we all baptized into one body…" (1 Corinthians 12:13). The baptism of the Spirit is therefore ecclesiological before it is individualistic.
Is the baptism of the Spirit a repeated personal experience?
Scripture presents the baptism of the Spirit as a foundational covenantal event connected to the formation of the church and the incorporation of believers into one body.
Are Pentecost, Samaria, and Cornelius separate Spirit baptisms?
They are best understood as progressive stages of one covenantal incorporation event opening the church visibly to Jews, Samaritans, and Gentiles.
Is speaking in tongues required as proof of Spirit baptism?
No. Tongues appear at key covenantal moments in Acts, but Scripture does not present tongues as the universal measure of spiritual life or maturity.
How is Spirit baptism different from being filled with the Spirit?
The New Testament speaks of believers being filled with the Spirit repeatedly for empowerment and faithfulness. The baptism of the Spirit is tied more specifically to the formation of the church as one body under Christ.
The church is not united merely by shared tradition, ethnicity, personality, or institution. The people of God are one body formed through the outpouring of the Holy Spirit by the exalted Christ.
A bishop is an overseer entrusted with spiritual leadership, protection, and care within the church of Jesus Christ.
Binding and loosing describe the church's ministerial authority to act in accordance with what heaven has established concerning the kingdom of God.
Jesus uses the language of binding and loosing in Matthew 16 and Matthew 18. In Matthew 16, after Peter's confession of Christ, Jesus declares: "Whatsoever thou shalt bind on earth shall be bound in heaven: and whatsoever thou shalt loose on earth shall be loosed in heaven." (Matthew 16:19)
The language appears again in Matthew 18 in connection with the gathered church and discipline.
In Jewish usage, binding and loosing often referred to forbidding and permitting — especially in relation to teaching, judgment, and covenant life. The phrases carried the idea of stewardship and responsible authority rather than magical power.
The Greek grammar in Matthew 16 and 18 is especially important. The construction strongly suggests heaven's prior authority in the action. The sense is not that the church independently creates spiritual reality and heaven responds afterward. Rather, the church acts in accordance with what heaven has already established.
The meaning is therefore closer to: "shall have been bound in heaven" and "shall have been loosed in heaven." This protects the passage from being treated as arbitrary spiritual power or autonomous ecclesiastical authority.
Christ alone possesses absolute authority over His kingdom. The church acts ministerially under His reign.
Does binding and loosing mean Christians can control spiritual reality?
No. The language reflects ministerial authority exercised under heaven's prior authority, not independent power to create spiritual reality.
Is binding and loosing only about demons?
No. In context, the language primarily concerns kingdom stewardship, teaching, discipline, judgment, and gospel authority.
Can the church bind and loose however it wants?
No. The church acts rightly only when functioning under the authority of Christ and in accordance with Scripture.
The church is called to exercise authority humbly and faithfully under the lordship of Christ. Christian authority is never autonomous or self-serving, but accountable to heaven and grounded in the truth of God's Word.
Born again refers to the new life given by the Holy Spirit through Jesus Christ.
Calling is God's summons by which He brings people to Himself and appoints them to walk in His purposes.
The church is the gathered people of God called through the gospel and ordered under Christ for worship, teaching, fellowship, discipline, and witness. The New Testament word ekklesia means assembly or congregation. The church is not merely all believers abstractly considered, but a visible gathered people living under the authority of Christ.
The New Testament consistently presents the church as a gathered people rather than merely a loose spiritual concept. The Greek word ekklesia refers to an assembly or congregation — a people called together.
For that reason, the church should not be reduced merely to a building, denomination, institution, or abstract collection of individual believers disconnected from one another.
The church is the people Christ gathers through the gospel. Jesus declared: "I will build my church…" (Matthew 16:18)
The church therefore belongs to Christ. He builds it, governs it, preserves it, and sends it into the world.
The church is both local and universal. In one sense, the church consists of all believers united to Christ through faith. Yet the New Testament overwhelmingly presents that reality visibly through gathered congregations living together under the authority of Christ.
The early church devoted itself to: apostolic teaching, fellowship, prayer, worship, discipline, generosity, and witness. Acts describes the church this way: "And they continued stedfastly in the apostles' doctrine and fellowship, and in breaking of bread, and in prayers." (Acts 2:42)
The church is therefore not merely a crowd sharing religious interest. It is a covenant people shaped by the gospel and ordered under the reign of Christ.
Is the church just a building?
No. A church building may house the church, but the church itself is the gathered people of God.
Is the church invisible only?
Scripture recognizes the spiritual unity of all believers in Christ, but the New Testament overwhelmingly describes the church visibly gathering for worship, teaching, fellowship, discipline, and mission.
Does the church replace Israel?
The New Testament presents believing Jews and Gentiles united together in one people through Christ. The church grows out of God's covenant purposes and expands through the gospel into the nations.
The church is not a religious service we attend occasionally, but a people to whom we belong under the lordship of Christ. Christians are called not merely to private belief, but to gathered worship, fellowship, service, discipline, and witness together.
Church discipline is the loving and ordered correction exercised by a local church to call the erring to repentance, protect the congregation, and restore fellowship where possible.
Church membership is the covenant commitment of a baptized believer to a local church under Christ, involving shared worship, mutual care, faithful service, and loving accountability.
Communion is the shared participation and fellowship of believers with Christ and with one another through the New Covenant.
A covenant is a binding relational order established by God through His promises, authority, and faithfulness.

Justification is God's act of grace, bringing the sinner into right standing—placing him upon the level ground of Christ's righteousness in the presence of God—received by faith alone.
The Kingdom of God is the rightful reign of God established in Jesus Christ, present now wherever He is trusted and obeyed, and awaiting full visible completion at His return.

Pentecost is the Jewish feast day on which the risen and exalted Christ publicly poured out the Holy Spirit upon His gathered disciples, launching the church into its worldwide witness. It marks not the invention of the church from nothing, but the Spirit-filled beginning of its public mission.
Pentecost (Feast of Weeks) occurred fifty days after Passover, when Jews from many nations gathered in Jerusalem. God chose this moment to pour out the Spirit, making the event public, multi-ethnic, and missional from the start.
The outpouring is inseparable from Christ’s ascension and enthronement. Peter explicitly teaches that the exalted Christ "shed forth" the Spirit (Acts 2:33). Pentecost is therefore Christ-centered, not Spirit-isolated.
The signs of wind, fire, and tongues were not ends in themselves, but visible markers that God had come to empower worldwide proclamation. The miracle centered on the nations hearing God’s works in their own languages, demonstrating that Christ’s lordship reaches every people without erasing linguistic or cultural diversity.
Pentecost should not be treated as "Babel reversed." At Babel, God scattered humanity to fulfill His command to fill the earth. At Pentecost, the gospel reaches those scattered nations, uniting them in Christ while preserving their distinct tongues and tribes.
Is Pentecost the reversal of Babel?
No. Babel scattered humanity to fulfill God’s creational mandate. Pentecost reaches the scattered nations with one gospel while preserving linguistic diversity, pointing toward Revelation’s multinational worship.
Is Pentecost mainly about ecstatic experience?
No. Peter’s sermon dominates Acts 2, centering entirely on Christ’s life, death, resurrection, exaltation, and lordship. The Spirit’s primary work at Pentecost was empowering public witness, not private religious enthusiasm.
Was the church fully mature at Pentecost?
No. Pentecost launched the church, but its structure, Gentile mission, and doctrinal implications continued developing through Acts and the Epistles.
Pentecost reminds us that the church exists for mission, not comfort. The same exalted Christ who poured out the Spirit in Acts 2 still empowers His people today to bear witness to the nations in His name.
