Consider everything Christ did for the sake of his Church, even to the point of sacrificing his very life on the cross for the sake of his Bride, giving us his Body and Blood, faithful to his promise to the very end. When a Catholic marries before the altar of God, this is the language of their commitment - it is united to Christ's language. But not so for a Catholic who instead opts for the standards and language of a man-made civil law contract which can be broken. If you find yourself in this situation, it is important that you talk to me (or your pastor) about what you need to do first in order to receive Holy Communion again.
This is, indeed, a wake up call for every one of us. We all risk profaning this most holy sacrament if we approach Holy Communion unworthily, unprepared or without thought of our life or lifestyle. St. Paul reminds us that we must examine our lives and lifestyles in the light of God's love, so as not to sin against the Body of Christ. And even though one may not be receiving Holy Communion for whatever reason, our life is never excluded from the reach of the Lamb of God who longs to enter under our roof, unworthy as we all are to receive him. Sometimes, we must wait for his word of mercy which comes when our soul is ready for healing.
