However this answer needs to be expanded if it is not to be misleading.All of us know Catholics who have suffered the trauma of separation and divorce. However the Church teaches, and has always taught, that a valid marriage between two baptized people is indissoluble and consequently no authority on earth has the power to end it."Today there are numerous Catholics in many countries who have recourse to civil divorce and contract new civil unions.In fidelity to the words of Jesus Christ - 'Whoever divorces his wife and marries another, commits adultery against her; and if she divorces her husband and marries another, she commits adultery' [Mk -12] the Church maintains that a new union cannot be recognized as valid, if the first marriage was.The Church's teaching on those who have "remarried" illicitly is clear and has been consistent for 2000 years.To dissent from the faith of the Church therefore is to oppose the commandments of God.This would be insanity, for it is God's law that must determine what is right and wrong, not man's desires.
If the divorced are remarried civilly, they find themselves in a situation that objectively contravenes God's law.Consequently, they cannot receive Eucharistic communion as long as this situation persists.For the same reason, they cannot exercise certain ecclesial responsibilities.Reconciliation through the sacrament of Penance can be granted only to those who have repented for having violated the sign of the covenant and of fidelity to Christ, and who are committed to living in complete continence." We are frequently asked whether divorced or separated Catholics may join the Catholic Unattached Directory.
Not even the Pope, Christ Vicar on earth, enjoys such power.It is important to understand that this truth is not something the Church invented, she is merely being faithful to the teachings of her founder, Jesus Christ. the God who threw the stars into their orbits and knit you together in your mother's womb, took our flesh and dwelt among us.
