TRINITY Sunday, is the next after Whitsunday; so called, because on that day was anciently held a festival (as it still continues to be in the Romish Church) in honour of the Holy Trinity.—The observance of this festival was first enjoined by the 6th canon of the council of Arles, in 1260; and John the 22d, who distinguished himself so much by his opinion concerning the beatific vision, it is said, fixed the office for this festival in 1334.
