Which event is described as the true establishment or birthday of the Christian Church?

• A. The Ascension
• B. The Resurrection
• C. Pentecost
• D. The Sermon on the Mount

Answer: (C)

Pentecost is understood as the moment the Christian Church is established and set in motion. After Jesus rises and descends to heaven, he sends the Holy Spirit to empower the apostles. On Pentecost, the Spirit comes with visible signs—tongues of fire and speaking in different languages—allowing the apostles to proclaim the gospel boldly to a diverse crowd. The response is immediate: about 3,000 people repent, are baptized, and join the new community. This marks the birth of the church as a distinct, Spirit-empowered fellowship of believers who begin to carry forward Jesus’ mission.

Resurrection and Ascension are foundational events in Jesus’ life, but they don’t inaugurate the church in the same way. The Sermon on the Mount is a set of Jesus’ teachings during his ministry, not the founding event of the church body. Pentecost uniquely ties together the Spirit’s empowering presence, the beginning of Christian mission, and the birth of a new communal fellowship.
