I am the girlfriend and quite frankly I am shocked by some of the responses.
Let me try to help. Unlike some of the people here I have no problem with Protestants. I myself was raised Protestant and I am a convert. I started to look more into my faith, read the Bible and realized that the Catholic Church was the only church for me. I’m not trying to convert you, but I would like to clear up some of your questions about the Catholic faith. Here I go:
Many people have expressed their faith that only faith will allow you to gain salvation. Catholics (and Eastern Orthodox) believe that good works are necessary to. Honestly I don’t think that this is a very big difference. Good faith will bring good works.
“What good is it, my brothers, if a man claims to have faith but no deeds? Can such a faith save him?” (James 2:14)
You don’t have to confess to a priest to be in good standing. However the Church believes that one must confess their sins. We know that the priest is not really forgiving their sins, only God can do this. However by confessing your sins you are showing a verbal commitment to God about how you are sorry for your sins.
“If you forgive anyone his sins, they are forgiven; if you do not forgive them, they are not forgiven.” (John 20:23)
I at first had a problem with the issue of Communion. I still do have issues with non-Catholics not being able to take Communion. However St. Paul makes it very clear that one must be in a state of grace before they can receive Communion. And since Protestants don’t really believe in Transubstantiation, Catholics are really doing them a favor by allowing them to not take Communion.
“Therefore, whoever eats the bread or drinks the cup of the Lord in an unworthy manner will be guilty of sinning against the body and blood of the Lord. A man ought to examine himself before he eats of the bread and drinks of the cup.” (1 Corinthians 11:27-28)
St. Paul also goes on to say how it is a sin to partake in Communion without acknowledging Transubstantiation.
“For anyone who eats and drinks without recognizing the body of the Lord eats and drinks judgment on himself.” (1 Corinthians 11:29)
So even if you don’t believe in this Catholics believe that they are helping keep non-Catholics from sin.
No to answer you original question. I don’t think that there is any problem with raising children in a household with two religions. You are both Christians so this really shouldn’t be a giant division. You basically believe in the same things. I would say that you let your children decide on their own. Not only will that save you the trouble of picking a faith for your children they will feel like they are not being forced into a particular faith.
I hope I have been of some help. I hope that you can see through your problems and make the relationship work.
