Yes there have been. Numerous ones. What makes you think that Jesus was not God? How do you reconcile the necessity for Jesus' death on the cross to be a divine action in order for it to be efficacious?
Most of you have bad ideas about Jesus as the second person of the Trinity, His efficacious salvation, and Mary the who is Mother of God.
Christ's death is efficacious. It is a once-and-for-all sacrifice. And leaving it there, it's all good. But tell me: do you see Mary as having any role in providing salvation? In mediating between God and men? In redeeming us?
