ok, try to understand this:
1.) Jesus did have two human parents, BUT Joseph was not His biological father. God was. So technically, Jesus had 2 fathers, one earthly, one heavenly.
2.) Mary was born to human parents. She was NOT immaculately conceived. She WAS a sinner, but held in high favor by God. Since Mary was born to human parents, and was fully human herself, she also was born with sin, as are all humans. She did NOT have magic powers that kept her sinless in the womb.
3.) The ONLY begotten child of God was Jesus. Not Jesus AND Mary. There is no misunderstanding this concept unless you happen to be a catholic. The bible itself says Jesus was the only begotten of God. Read John 3:16.
4.) As long as you keep believing that Mary WAS immaculately conceived, satan's gonna drag you down further and further until you end up where he is.
You want to be a true Christian? Stop believing that Mary was immaculately conceived, because no TRUE, honest christian believes any of that poppycock..
The RCC is a false religion, and the pope is a false prophet, and they worship satan, NOT God. The RCC is evil and the sooner you realize that, the better off you'll be..
