It may be asked why the Baptist sought baptism since he had been cleansed and sanctified in his mother’s womb, and so he had no need of further cleansing as we read in St. Luke (1. 15): ‘And he shall be filled with the Holy Ghost even from his mother’s womb.’ My answer is he desired the Character or seal, and the beauty that he knew would be given by Baptism, since he also knew well that he was sanctified, not stained by sin. Therefore he said to Christ: ‘I ought to be baptised by thee.’ It is supposed, for the same reason, that the Virgin was baptised, although conceived immaculate; the Apostles also were baptised, as St. Augustine says (Epist 108). The holy prophets did not receive this seal, this beauty. So, in heaven you will be able to distinguish: this man was baptised, this was not.
