2 Cor. 1:23 (V)
that it is not out of scorn for you nor puffed up with pride of moral wisdom and the contempt of others that I have undertaken, along with other sages, the solemnity of the Paschal feast. For in the first year in which the cycle of 532 years began to be celebrated by our party I did not accept it, but remained silent; I dared neither to praise nor to condemn it, since I believe that I by no means surpass in knowledge the Hebrews, Greeks and Latins, whose languages, as Jerome says, Christ consecrated in the inscription of HisThess. 5:21
before I tried it, I did not disdain it. Hence, having cloistered myself for a year and having entered the sanctuary of God (that is sacred Scripture) I studied as much as I was able, then I examined the histories, and finally the cycles which I could find.
