In today's Liturgy of the Hours, there is a beautiful reading from the Acts of the Apostles (5:30-32). By that reading, we are reminded that Jesus is at the right hand of the Father, bringing us repentance and forgiveness for our sins.
Unfortunately for many Christians, the idea that they can never be snatched out of the Father's Hand is what rules their minds and hearts. They cannot lose their salvation, they think, and so fall into the sin of Pride...the sin that basically tells them that all they have to do to be 'saved' is to ignore everything in Holy Scripture that urges them to do good, to pray, to practice the liturgy and (most important) to eat and drink of the Flesh and Blood of Jesus Christ - for without that they shall have no life within them.
The saddest part of walking away from the Catholic Church is the walking away from The Eucharist. It is sad to leave the community of the Church He founded, but to leave the chance to follow His specific word, His specific instructions based on a faulty and historically recent interpretation of some sections of Holy Scripture is just very, very sad.
So today I pray for all those who have fallen away from the Fullness of Truth. May the fires of the Baptism rise up within their hearts and lead them Home to Rome.
