That would be like saying that using birth control leads to abortion and gay marriage.
That is EXACTLY what Michael Voris is saying.
Wow. Those are some pretty big jumps.
I am neither pro abortion nor pro gay marriage. I don't care what the state does regarding civil unions, or civil marriage. Abortion is the taking of an innocent human life. I do not see that having any effect on the Church's teaching on the Sacrament of Matrimony, nor its practice administering that sacrament.
However, the use of birth control is a very big jump to abortion and gay marriage.
