Well, i just responded to your earlier post and say this one. It seems that either this a serious issue on your heart, or you are trying to find a way to smear his priesthood, or the priesthood in general, or just smear your cousin or both. In any case, it would appear you have strong feelings, and are upset about it.
If you are hurt by him separating himself from part of your family , then think how he feels by your agnosticism and conversion. You already separated yourself in a very painful kind of way. I realize its not quite the same because despite our differences family and friends should always communicate. But you kind of separation is even more harmful to yourself and I am sure he is very concerned about it. And perhaps your lack of faith conversion in the family is damaging to his faith and needs to remove himself from this thinking. Perhaps he is going through a crisis of faith and your communication with him is too difficult right now.
In general , it sounds as though your family had a very varied experience of the faith, so it makes for some interesting family dynamics , I am sure. If your cousins behavior is troubling to you, your falling from the faith is upsetting to him as well. But your posts on this comment board are interesting to me too. You sound rather upset and maybe even little desperate as well as you posted two separate time. I dont mean to be cruel, but perhaps that is something your cousin is responding to also.
If you converted to Protestantism and are now agnostic, I would further suggest you do have an issue with faith. Even as laity, dealing with someone whose faith life is a challenge is difficult. You would think such challenges are what priests are supposed to deal with. However , when it involves your own family it becomes very difficult. In certain professional fields , such as psychology or medicine, you are NOT even supposed to practice on your family members. Lastly, not to sound rude, but as I said before, posting twice here seems a little weird.
My last comment is that your cousins behavior does not sound ideal. It seems understandable. Your family as a whole seems to have some issues with faith, good and bad, as many families do these days. Given these dynamics, I would suggest you start to address this issue by examining your own issues as to why his behavior has caused you to post 2x on a Catholic website when you dont even have faith in the Church anymore. Perhaps “Thou dost protest too much”? Open your heart to the Holy Spirit! See what happens. God bless, best wishes for you and your family!
