I recommend this book if you are a Christian and see friends losing their faith because of this application of deconstruction.

I didn't have the term at the time but I went through a very deep questioning phase for many of the same reasons many people do. Seeing the flaws in people and transferring that to God. A better phrase that I like to describe this journey is spiritual formation. Basically testing and learning for yourself instead of just accepting the beliefs of others or the church. Working things out as it says in Philippians 2:12.
