Just being Catholic doesn’t guarantee you are a Christian. You can be a Catholic and not have Christ in your life. Same way with any other church. It all comes down to WHO IS CHRIST TO YOU? Have you put your faith and trust in Him or in the church?
You said: Have you put your faith and trust in Him or in the church?
It’s His Church so faith in Him and His Church go hand in hand.
Without His Church you can still have faith in Him, but it’s a defective faith. In order to attain fullness of faith in Jesus Christ you need His Church.
