Knowing theological history is good. Most fundamentalists though seems to think Jesus died and then Martin Luther appeared fully formed out of Gutenberg’s printing press. Um, not. So anyway, for the belief geeks, atheists, and agnostics, a little something to counter faith-based arguments about civil marriage equality:
It took more than three centuries after Jesus’ death for the Christian Church–in 343, under the co-Emperors Constantius and Constans, sons of Constantine the first Holy Roman Emperor–to ban same-sex marriage.
But Constantius was a Christ-denying heretic who did not believe that Jesus and God were the same. A follower of the heresy of Arianism from 338 on, Constantius believed the Son was created and thus not equal to God, and actually less than God, which went against orthodox Christian beliefs, including those held now.
In 359 at the council of Ariminum, Constantius revoked the Nicene Creed, the central foundation of Christianity, both Catholic and later Protestant, which states that Jesus is "of one substance with the Father."
So why do Christians accept as law what this heretic said? And don’t get me started on Bible verses.
