Question 144

What happened at Pentecost?

Answer

Fifty days after the Resurrection at Pentecost the glorified Jesus Christ poured out the Spirit in abundance and revealed him as a divine Person so that the Holy Trinity was fully manifest. The mission of Christ and of the Spirit became the mission of the Church which is sent to proclaim and spread the mystery of the communion of the Holy Trinity.

“We have seen the true Light, we have received the heavenly Spirit, we have found the true faith: we adore the indivisible Trinity, who has saved us.”
