Hi, guys —

I'm very worried. I am currently taking classes to become a Catholic but haven't been accepted into the Roman Catholic Church.

I went to Mass last week and received Holy Communion. When I came home I told my partner, who is a Catholic, said it was a mortal sin to receive Holy Communion without first going to Confession.

I feel so ashamed and upset that I have disrespected the Church. I feel so awful about it.

Please help me as I don't know what to do. I want to be a Catholic more than anything else and the last thing I wanted to do is disrespect the Church.

Dear WorriedNewCatholic,

First, Welcome to our family!

Your Catholic friend, like many, has been poorly catechized and is wrong.

From the Catechism:

1857 For a sin to be mortal, three conditions must together be met: "Mortal sin is sin whose object is grave matter and which is also committed with full knowledge and deliberate consent."

So it must be:

  1. grave matter
  2. committed with full knowledge, and
  3. deliberate consent

If one of these criteria is missing, it is not a mortal sin.

Mistakes and accidents will happen. This is just part of being human so don't worry about this.
If it still bothers you, once you enter the Church you can bring the topic up in Confession but don't worry about it.

Second, even if your Catholic partner was correct, though this was an accident, non-Catholics can't receive the sacraments until they become a Catholic so you could never go to Confession anyway.

Again, don't worry. The Lord knows a good heart and soul when he spiritually sees one : )

What would be correct is to say:

Any Catholic who is conscience of known mortal sins they have committed has to go to Confession first before receiving the Eucharist. Receiving the Blessed Sacrament with known mortal sin on your soul just spiritually damages the Church and that's something we don't need.

  • Have they given you a Catechism of the Catholic Church to study?

If not, and you are interested, I may be able to help.

Just reply and tell me.
