Sounds like a copout to me
No book chapter and verse ?
then No validity
Your faith's chain of custody started and ended with you silly. Real Christians can actually track the chain of custody of their faith to Christ and thus God. But you have no such way to do so, if your faith didn't originate in and with the truth we find in Christ to the reality of God the Father, so you have NO such assurance at all. If you need help to understand the Christian faith, then at least ask someone who shares in Christ's faith and not just their own.
However, I am starting to think that you and others in this forum like you are just atheists pretending to be Christians in order to discourage belief in the truth and reality of God.
