Thanks for the question, Lisa. This is one of the most misunderstood things in the Church today. Yes, you can receive Communion if you are divorced. You may not receive if your marriage hasn’t been annulled and you are involved with or married to someone else.
In the eyes of the Church, a legal divorce does not end the marriage. It is still a sacramental marriage (meaning a sacrament took place) So you can receive Communion as you did in your married life. (assuming you are free from any other mortal sins).
The problem becomes when you are involved with someone or remarry without an annulment. See, cause in the eyes of the Church you are still married to person number one. Therefore, you aren’t free to marry anyone else.
In order to do so, you must seek an annulment. This is a process the Church uses to decide whether or not a sacramental marriage occurred. Many times and for many reasons it might not have been a sacramental marriage and it is annulled. This means you are fee to remarry and to continue to receive Communion. Does that make sense? If not, I encourage you and anyone else with questions about annulments to ask your parish priest. If you are unable to do so, contact me and I will put you in touch with someone who can help.
