Vigil & Confessions: May 30, Saturday at 6:00 p.m.
Liturgy: May 31, Sunday at 10:00 a.m.
This is the feast of the Glorification of the Holy Trinity, in commemoration of the Descent of the Holy Spirit upon the apostles. Inasmuch as this great event took place on the fiftieth day after the Resurrection of Christ, this feast always occurs on the fiftieth day after the feast of Pascha; hence, it always falls on a Sunday.
On the fiftieth day after Jesus Christ's resurrection, apostles with the Mother of God and other believers were together and prayed. In the third hour from the start of the day suddenly there came from the sky noise, like from a strong wind, and filled the entire house where they were, and tongues of flames appeared and came to rest on each one of them. All were filled with the Holy Spirit and began to glorify God in the languages which before they did not know. Read more about the feast HERE or read more at pravoslavie.ru.
