Which event marks the birthday of the Church?

• A. Easter
• B. Ascension Day
• C. Pentecost
• D. Christmas

Answer: (C)

Pentecost is the moment the Holy Spirit is poured out on Jesus’ followers, empowering them to proclaim the gospel and form a distinct community of believers. After Jesus’ resurrection and ascension, the disciples are gathered in Jerusalem, and on Pentecost the Spirit enables them to speak in various languages and boldly witness to the risen Lord. This outpouring creates the church as a living, missionary body—the followers of Jesus united by the Spirit and beginning the mission to all nations, which many traditions celebrate as the church’s birth. The other events mark different aspects of Jesus’ life: Christmas recalls the Incarnation, Easter celebrates the resurrection, and Ascension marks Jesus’ return to heaven; none of these inaugurate the church in the same constitutive way as Pentecost.
