So if I am divorced, then remarried, and then divorced again, am I permitted communion?
You see, Catholics are not forbidden divorce. Only remarriage, which you have apparently taken care of, but weren't really really married anyway.
However, in starting your life anew, I urge you to consider annulment, or perhaps even the Pauline Privilege, which is why Catholic Royals advised unsatisfactory spouses to accept the veil or Holy Orders, and in earlier times, married converted Christians were allowed to dump the unconverted partner.
Please consult a Canon Lawyer, Vinnie the Hit Man, or, join another church.
Be advised although Freepers are Holy Terrors for the most part, none of us is exactly recognized as a Certified Vatican-Licensed Spiritual Advisor. I did stay in a Holiday Inn Express once, though.
Yes. Assuming you're in a state of grace.
