Let me preface by saying that I
still respect what the RCC stands for on many issues, I respect the theology written, and many of the people that are there. The priest that I went through RCIA with and attended his parish for close to 10 years was and is a fantastic man. The other priests at that church were also truly men of God, if I were still in the same life situation I might still be Catholic. That parish is truly alive with the Spirit and is a wonderful Christian home.
In essence, I had a divorce based on infidelity from my then wife. This caused a faith crisis in general and caused me to look at my faith from the roots up. Several of the issues I had with the RCC all along remained: Papal infallibility, the sex scandals, Pope Francis in general, etc. When I looked at the Lutheran church I found that most of what I liked about the RCC remained, but the things I did not like were not there. Some things are still missing, things that the RCC does well, but I can't go back due to a number of reasons.
I'll send you a PM with a longer reply, if you want to start a thread about it that would be fine with me, my story is not hidden - it is played out over these forums over the years. But it probably exceeds the scope of this thread.
