Hi Don,

Good question.

No. These would be invalid marriages, outside of the will of God, as expressed through the authority of His Church, which Christ Himself has given Her.

Receiving Holy Communion while being in an invalid union would be a contradiction — seeking intimacy with Christ while rejecting His moral law on marriage.

Seeking to remedy the marital situation is the first step toward union with God through His sacraments.

Peace,

Paul
