Catholics say Joseph and Mary never had any other kids yet the Bible notes they did.
Catechism 969:
“Taken up to heaven she did not lay aside this saving office but by her manifold intercession continues to bring us the gifts of eternal salvation”
Nonsense.
Jesus had relatives, “brothers” in some translations. Possibly cousins, possibly sons of Joseph by a previous wife. But there is NO assertion anywhere in Scripture that Joseph fathered children by Mary. Absolutely none.
At the Annunciation, Mary said, “...I know not man...” I.e., she had taken a vow of virginity, and she DID NOT EXPECT to be having relations with Joseph. There is no suggestion anywhere that the vow was violated.
