Please allow me to get something off of my chest for a moment. If this isn't about you, then please feel free to mentally change the "you" to the pronoun of your choice.
I don't personally care whether you consider Catholics to be Christians or not. I don't care how well meaning your invitation for my children to "come to church with my kids" is. I don't personally give a rat's patoot as to how much fun your children have at "kid's church" on Wednesday nights. I think that what you are doing is wrong and not a little bit evil.
I am on to your AWANA program which encourages children to bring an "unsaved friend" to church with them. I know your child earns points and prizes for each friend they manage to bring along. I have no interest in helping him earn those prizes and I think your theology is seriously flawed.
It is wrong to take a small child and poison his mind against the faith of his parents. It undermines the very security of his whole world when you tell him that the Truth his parents have raised him in is leading him to Hell. How dare you attempt to place a wedge between my husband and myself and our child and use the Word of God as the mallet to drive it in. Evil, evil, evil.
I appreciate that you think you have his best interests at heart, that you only want him to know God as you know Him, and that you see me as the obstacle standing in your way. You're right!!!! I am that mountain. If you are seriously worried about my child's immortal soul, then you need to come to me. Do not attempt to destroy our family, but rather, approach the people in charge and try to persuade us all. If you have something to say to my child which can not be said in my presence, then perhaps you need to be doing some serious soul-searching and ask yourself what is wrong with your message that it is not fit for my ears.
My children are not now, nor will they ever be a party to your sick little heretical game. If you want my son to come anywhere near your church, then you better be prepared for his Mama to come, too. I'll be bringing my Bible, my Rosary, the One True Faith, and the entire Communion of Saints along with me. Still interested? No? Then BACK OFF!
