Wynn,

The practice is based on the nature on the Eucharist itself, it is a sign of unity and communion.

Those who don't share our beliefs are not in full communion with us, so it would be a false sign.

For those who do share our beliefs, baptism is the entry point. It is analogous to marriage:

first the vows, then the consummation of the marriage.

Peace,

Bob Kirby

Dear Wynn,

Just to add to Bob's answer, your question implies an interest in receiving Holy Communion in our Church.

If that is the case:

• study our faith
• look into what we believe and why, and
• become a Catholic.
  

It's great!

Mike
