If you are civilly divorced but have not remarried or were validly married in the Church after receiving a declaration of nullity for your first marriage, then, yes, you may receive the Sacrament. If you have remarried outside of the Church or have entered into a cohabitating relationship, then those predicaments must be addressed before you can receive absolution. Pope John Paul II addressed this situation in 1981. “The church reaffirms her practice, which is based upon sacred scripture, of not admitting to Eucharistic communion divorced persons who have remarried. They are unable to be admitted thereto from the fact that their state and condition of life objectively contradict that union of love between Christ and the Church that is signified and effected by the Eucharist. … Reconciliation in the sacrament of penance, which would open the way to the Eucharist, can only be granted to those who, repenting of having broken the sign of the covenant and of fidelity to Christ, are sincerely ready to undertake a way of life that is no longer in contradiction to the indissolubility of marriage. This means, in practice, that when, for serious reasons such as, for example, the children's upbringing, a man and a woman cannot satisfy the obligation to separate, they ‘take on themselves the duty to live in complete continence, that is, by abstinence from the acts proper to married couples’” (FC 84). If you’re in these circumstances, you are encouraged to talk to a priest in the light of God about your present situation and possibly begin an investigation of whether your first marriage was valid.
