I am sure I'm not the only one who has ever gone through this, and probably not the last. I was born/raised Catholic - and quite involved in the Catholic church, all the ways until the end of my university degree. After graduating from university, I sort of fell away from the church, spending time around the wrong people, wanting to explore other things, and really not dealing constructively with some of the issues I had around my upbringing (which I unfortunately linked to the church).
I moved to a new town three years ago, and made some friends through school (doing further university schooling now). I made a friend who I've gotten to know quite well since we met in class. She goes to a Protestant church, and I would go with her now and then, just to see if there was a "different" way to learn about God. During this time, I also researched the different religions and cultures of the world. I have mentioned to her in the past my "issues" with the RCC, which I realize now were simply due to erroneous beliefs that I got from who-knows-where, maybe just not paying enough attention in Catechism when I was younger. I'd become a more frequent visitor of her church the past few months.
However - some terrible events have happened in my life recently that have made me realize the error of my ways. I started researching the Catechism and basic beliefs of the RCC. I truly missed a lot about it - and I never felt quite comfortable in my friend's church, because I was hanging on to some Catholic beliefs. In any case, with much courage, I finally went to Confession, and after speaking with the priest about the journey I've been through, he agreed that I may return to the church after doing my penance, which I have, and have since received the Eucharist.
Basically, my friend has disappeared from my life. When I told her I was returning to the Catholic church, she asked for an explanation. She's been a great friend to me - religious beliefs aside - so I sent her an email stating my reasons for returning. She hasn't replied, and I know our friendship is over. I know that God wanted me to return to the Catholic church, but I am just having trouble grasping the fact that if we have the "same" God, why is she so upset? If she was worried about me being saved, I still believe the exact same things she knew I believed from the start.
I've never lost a friend over religion or spiritual beliefs before - I know it happens commonly, but it feels pretty terrible. I've ended friendships for other reasons (i.e. difference of morals, etc), but never due to what church a person attends.
While I respect other forms of Christianity, I believe that what the Catholic church teaches to be true, in case anyone reads this and gets the impression that I'm a wavering Catholic. Definitely not anymore!
