This homily (for the 27th Sunday in Ordinary Time) by Fr. Eric M. Andersen, Sacred Heart-St. Louis in Gervais, contains a very clear and beautiful description of the Sacrament of Marriage as we see it unfold in the Garden of Eden with our first parents, Adam and Eve.
This man, Adam, was not simple-minded. You may recall from a few weeks ago that Adam was created with infused knowledge from God. Therefore, he was knew the mysteries of creation and the wisdom of God. He was filled with the Holy Spirit, and his intellect was far superior to ours because he was created without sin. There was also no death, so his body was immortal and his soul was immortal. All this is outside of the garden.
The Church is bound to the words our Lord spoke in the gospel today about divorce and remarriage, and we cannot change that. The Church assumes that all marriages are valid. Therefore, there is no such thing as divorce for Catholics. But what happens to those who have divorced and remarried? The Christian life is all about reconciliation with God. So how do we reconcile this situation? The Church has no power to nullify something that is valid, but if there is something that invalidated the marriage from the beginning, the Church can identify that and formally declare in writing that the marriage was never a valid sacrament. Yes, the marriage happened and the children are legitimate. It does not erase the marriage. It does not heal all the wounds of those involved, but it does begin the healing process making it possible for both parties to reconcile with God. If you or someone you love is in this situation, have them come and talk to me. God wants you to be healed and I want to help.
