Luke 1:60

The holy Evangelist has especially remarked, that many thought the child should be called after his father Zacharias, in order that we might understand, not that any name of his kinsfolk was displeasing to his mother, but that the same word had been communicated to her by the Holy Spirit, which had been foretold by the Angel to Zacharias. And in truth, being dumb, Zacharias was unable to mention his son's name to his wife, but Elisabeth obtained by prophecy what she had not learnt from her husband. Hence it follows, And she answered, &c. Marvel not that the woman pronounced the name which she had never heard, seeing the Holy Spirit who imparted it to the Angel revealed it to her; nor could she be ignorant of the forerunner of the Lord, who had prophesied of Christ. And it well follows, And they said unto her, &c. that you might consider that the name belongs not to the family, but to the Prophet.

Now in an allegory, the celebration of John's birth was the beginning of the grace of the New Covenant. His neighbours and kinsfolk had rather give him the name of his father than that of John. For the Jews, who by the observance of the Law were united to him as it were by ties of kindred, chose rather to follow the righteousness which is of the Law, than receive the grace of faith. But the name of John, (i. e. the grace of God,) his mother in word, his father in writing, suffice to announce, for both the Law itself as well as the Psalms and the Prophecies, in the plainest language foretel the grace of Christ; and that ancient priesthood, by the foreshadowing of its ceremonies and sacrifices, bears testimony to the same. And well doth Zacharias speak on the eighth day of the birth of his child, for by the resurrection of the Lord, which took place on the eighth day, i. e. the day after the sabbath, (septimam sabbati.) the hidden secrets of the legal priesthood were revealed.
