Pentecost Sunday

Pentecost Sunday is one of the most ancient feasts of the Church, celebrated early enough to be mentioned in the Acts of the Apostles (20:16) and St. Paul’s First Letter to the Corinthians (16:8). It is the 50th day after Easter (counting both Easter and Pentecost).

On the day of Pentecost when the seven weeks of Easter had come to an end, Christ’s Passover is fulfilled in the outpouring of the Holy Spirit, manifested, given, and communicated as a divine person: of his fullness, Christ, the Lord, pours out the Spirit in abundance.

On that day, the Holy Trinity is fully revealed. Since that day, the Kingdom announced by Christ has been open to those who believe in him: in the humility of the flesh and in faith, they already share in the communion of the Holy Trinity. By his coming, which never ceases, the Holy Spirit causes the world to enter into the “last days,” the time of the Church, the Kingdom already inherited though not yet consummated.

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.
