There are times that separation and a civil divorce is justified but this does not invalidate the existing marriage. As Christians do we take the words of our Lord seriously or are we just play acting?
So are we disagreeing specifically about annulments now?
Are you saying if a woman is divorced by her husband she isn’t allowed Communion anymore? Is this what you are saying? What about a couple who converts to Catholicism and they are both divorced and remarried to each other? Are you going to tell them, “Sure you can join our church but we won’t let you take Communion”, and deny them the very sacrament Catholics claim is essential to salvation? Hey...if that’s the case, send them to the nearest Evangelical church we and God accept all sinners who want to be saved by grace!
