Donxyz,
The parent must know, love, and serve the Lord with their whole heart, mind, soul, and strength. This can be expressed most fully by knowing and living all that is Catholic. The parent’s teaching and example are paramount. The Catholic faith is rich, deep, and beautiful beyond anything else because it has been founded and established by Jesus. Learn everything you can about the faith and pass this on to your child. Teach the child the meaning of holiness and why it is important that we be holy as the heavenly Father is holy. Get to know scripture and get your child interested in it as well. Your child will naturally gravitate to these things by the power of God’s love and grace.
