Stick to the Catholic church, do this not only for you but your family. The Catholic church is so precious and so important in so many ways.
I read your post and i understand your concerns. You cannot think as a human but let the Holy Spirit guide you. God will inspire you to use the right words for your sons, in the mid time, pray and fast. I was the only one in my family going back to church. Short story, my husband converted and my child has a passion about the teaching of the church. Mother Mary is truly amazing and wonderful. Start those rosary now.
Don’t worry, your sons will follow. They will understand that it is far more important to be faithful to God.
In one of mother Mary message, i recalled reading that the reason there are many Christian church was because the devil did this to split the church. Protestant started only because the King wanted to be able to divorce. The Catholic church is the only one that have all the Seven Blessed Sacrament. Only an ordained priest can truly bring the Christ body and blood in the Holy Host and wine. Mortal sin can only be absorbed by confession. Another amazing miracle, is that Christ speak through his priest. No wonder that you had a good experience, VALUE his messages always. I am re-learning my religion, i also was raised Catholic and take the side track for the longest time, when i finally got it that i was deeply wrong, i simply pray and Mother Mary did all the work for me concerning my family.
Trust in God and have faith, resume to the Catholic church. Jesus is waiting for you with his arm open. I bet your guardian angel will have such a party with our lord.
Blessings and love!
