immaculate conception v. virgin birth

Immaculate conception is the Roman Catholic dogma that the Virgin Mary was conceived, through sexual intercourse, without the taint of original sin. In this way, it was possible for Jesus, despite having a human mother, to be completely free from sin himself.

Virgin birth refers to the belief that Mary miraculously gave birth to Jesus while remaining a virgin. In other words, Jesus had no human father and was conceived through the Holy Spirit without sexual intercourse.
