Im a Catholic, who was not married in the church. To get and receive the sacraments, my marriage must first be blessed by a priest, and then I need to do a full confession. Thats the way they roll there. Its protocol for doing it right. In their agenda.
Going to Mass is great. I still go, tho no longer an active member. If you feel wine may trigger you, just pass on it. I personally dont do either. Communion, or wine. But, Mass is a good thing!
