Catholics and Marriage between the people of other Religion

Fr. Xavier Khan Vattayil states:

What should be the stand of a child of God concerning mixed marriage?
1. Love those who belong to other religion like your own brother or sister. But do not choose anyone of them as your spouse.
2. Do not fall in love with people of other religion.
3. Do not encourage anyone towards mixed marriage. Try to dissuade them.
4 . Adopt the healthy approach recommended by the church with regard to marriage. The church does not advocate mixed marriage. Be aware of the teachings of the church regarding mixed marriages.
5. Inculcate in children the values and convictions related to this subject while bringing them up.
6. Incorporarate the stand of the church concerning mixed marriages in your teachings.
7. In case mixed marriage becomes inevitable in certain case, go ahead only if the partner is willing to accept Christian faith and become a member of the church. Also think whether your action will serve as a bad example to others.

Mathew 18:6 “If any of you put a stumbling block before one of these little ones who believe me, it would be better for you if a great millstone were fastened around your neck and you were drowned in the depth of the sea.”

What is wrong if I marry someone whom I like from other religion?
“We are allowed to do anything but not everything is good. We are allowed to do anything, but not everything is helpful.”(I Cor: 10:23)
“Those who fear God will seek the will of God” (Sirach: 2:16)
It is God’s will that we must seek and not ours.
