Constantine

[Sethomas]

The idea that Jesus had children was only popular among the Gnostic Christians, so it's highly unlikely that anyone such as Constantine would have to excert any effort into debunking it. It's asinine to say that the Dead Sea Scrolls were deliberately left out because they weren't even discovered until the 20th century. The Old Testament adopted by the early Christians was simply the Jewish texts used until the Jewish Synod of Jerusalem around the year 70 AD, hence it includes books of the Septuagint that were dropped out of Torah and abandoned by Protestant reformers. If memory serves, Constantine wasn't even present at the Council of Nicea.
