I am told I cannot receive Eucharist at the Catholic mass, so I go up each time and cross my arms and ask for a blessing. Wish they would accept my faith in the basic Christian tenets as being acceptable for being able to participate in Communion. You're confusing things a bit here. So that part shouldn't trouble you.
Communion is a somewhat different matter.
For us to offer communion to anyone without requiring doctrinal consent would be dishonest for us and in our opinion a corruption of communion as a symbol of unity in the Body. It ought to be painful, because you are a thoughtful, committed, conscientious Christian who values unity and oneness, as Christ did. But should you decide to become Catholic, you will be immediately welcome at the Lord's Table. Until then, no one has any business looking down their nose at you. That was a thrill because I felt I played a key role in the whole service, even though I couldn't yet take communion.
