An ample reply has now been given to what he advanced respecting the words before they came together, and he knew her not till she had brought forth a son. I must now proceed, if my reply is to follow the order of his argument, to the third point. He will have it that Mary bore other sons, and he quotes the passage, “And Joseph also went up to the city of David to enroll himself with Mary, who was betrothed to him, being great with child. And it came to pass, while they were there, the days were fulfilled that she should be delivered, and she brought forth her first-born son.” From this he endeavours to show that the term first-born is inapplicable except to a person who has brothers, just as he is called only begotten who is the only son of his parents.
