Good morning, Rose;
Not all Catholics are saved but there are some parish members who are saved.
Correct doctrine of God's Word, teaching and raising up empower the Saved with wisdom and knowledge from the Scriptures.
Where the devil is deceptive is when we replace discipline in obedience and relationship toward Jesus with traditional rituals. How many do the sign of the cross, receive penance of prayer after a confessional without thinking about it?
There is more to this. I have to scoot right now but will return and expound later.
God bless you, Rose and your entire family.
Bob
