As far as time in this world goes, yes. If you don't think so, then you'll have to explain how Jesus existed, before He was born.
"So this makes Mary the Mother and progenitor of the Trinity. Wow. No wonder you guys worship her."
I don't worship Mary. I respect her. Mary is the Mother of God, because she bore Jesus. In order for God to be a trinity, the man part must exist. You do know that all men are trinity right?
Holy Cow! You do believe that nonsense! You do believe that the Trinity only came into existence in 4 B.C.!!!!! You don't believe that the Trinity is eternal!! You don't believe that Jesus Christ is eternal!!!!
How many of your Catholic buddies believe this nonsense? Are you just making this up as you go along, or did someone tell you this is what you are supposed to believe.
