The fiftieth day following Easter, commemorating the descent of the Holy Spirit on the Apostles; Birthday of the Church.

• A. Sacrament
• B. Original Justice
• C. Pentecost
• D. Heaven

Answer: (C)

Pentecost is the feast that marks the descent of the Holy Spirit on the Apostles and is celebrated as the Church’s birthday, occurring fifty days after Easter. This event, described in Acts, empowers the Apostles to proclaim the gospel to people from many nations, signaling the start of the Church’s mission to all. That specific meaning fits the description provided in the question, making it the best choice. A sacrament is a religious rite, but Pentecost refers to a festival and its transformative event, not just a rite. Original Justice speaks to humanity’s state before the Fall, and Heaven refers to the final destiny after life on earth, neither of which capture the fiftieth-day celebration and its impact on the Church.
