I must say that coming to Church or your salvation is an individual decision. I understand the scripture as for me and my house we shall serve the Lord. Is a scripture often used by parents to enforce it on their children. However, this is the entire scripture:
"But if serving the LORD seems undesirable to you, then choose for yourselves this day whom you will serve, whether the gods your forefathers served beyond the River, or the gods of the Amorites, in whose land you are living. But as for me and my household, we will serve the LORD." Joshua 24:15
In my home my children were required to come to church as a family, as well as sitting down for dinner once a week. This is because of my belief in the scripture: Proverbs 22:26 Raise up a child that they should go and when they are older they shall not depart from it.
Ephesians 6:4 Fathers, do not exasperate your children; instead, bring them up in the training and instruction of the Lord.
Now, as for as spitting out the communion I am about to tell you the oddest thing. You placed yourself in better standing. This is why I state that.
7 Whoever, therefore, eats the bread or drinks the cup of the Lord in an unworthy manner will be guilty concerning the body and blood of the Lord. 28 Let a person examine himself, then, and so eat of the bread and drink of the cup. 29 For anyone who eats and drinks without discerning the body eats and drinks judgment on himself. 30 That is why many of you are weak and ill, and some have died. 31 But if we judged ourselves truly, we would not be judged. 32 But when we are judged by the Lord, we are disciplined so that we may not be condemned along with the world.
33 So then, my brothers, when you come together to eat, wait for one another— 34 if anyone is hungry, let him eat at home—so that when you come together it will not be for judgment. About the other things I will give directions when I come.
Also, communion is not just a catholic thing. All biblical Christians are told to do this in rememberance of Me, says Jesus.
1. If this is not coming from your heart and your relationship with Christ then it is in vien.
Lastly, because I am not Catholic and you or at least your family is I have enclosed a link that goes further into the Catholic Church Law.
