The answer
Although the sin is forgiven, one has to deal with its consequences. A girl who gets pregnant and have a child out of wedlock; will not get rid of the child nor deny his presence because she has repented. Likewise, loss of virginity has its consequences: it can be a reason for annulment of marriage later on even after repentance and confession. That is why the church has to know before hand.Answered by His Eminence Metropolitan Youssef (opens in a new tab)
