Note 20 — Chapter V · THE STRUGGLE WITH BECKET
Reading edition
Gervase of Canterbury (Opera, i. 171) says that Thomas instituted the feast of the Holy Trinity. It would seem that the Sunday following Whitsunday was already sacred to the Trinity, but that he gave to the feast a position which it had not held before in England, and which it did not attain on the Continent till a much later date.
