Like wizr, I also cited God’s removal from public schools as one reason and I stand by it.
I can remember learning Christmas Carols and participating in Christmas Biblical plays in Elementary School, which are banned today. Some of those plays were better and just as religious as the plays we put on at St John’s parish for our parents.
I would not have known the Christmas Carols, but for the public school. I certainly didn’t learn them at Mass on Sunday.
It is not the function of any church to teach you how to sing a christmas carol or put on a play. Church is where you go to worship God, as He commanded.
From both your comments, I get the impression there was little discussion of faith at home. Here again, it is YOUR responsibility to learn the faith and transmit it to your children, while bringing them to church on Sunday to worship God.
While neither of you has specified to which church you belong, I believe ALL christian churches follow the Apostles Creed. As such, you may want to begin here. It is the same for ALL christian faiths. To know your faith is truly liberating! It brings great joy and peace.
