I’ve been asked this question before, and I do find it to be an entertaining one for myself to figure out. Well, I will admit that my views are somewhat close to Catholic views, and I take to Lutheran views on the sacraments and justification especially (I don’t yet see anything I disagree with if I’m honest). I do not go to a Lutheran church, nor was I raised as such, but it may be where I stand.
When I first started to take an interest in theology (I was around 9 or 10), I was very ignorant of it coming from all sides. However, I developed an Arian and semi-Pelagian downright heretical theology saying “the councils got it wrong.” I’m not justifying it, but I only rejected it within the past year or so (I’m relatively young, so perhaps it was permissible?). I do regret it now, and if I could go back in time, I’d convince myself otherwise. But I can’t do that!
I know you didn’t ask to hear about my entire theological journey, but a considerable reason I’m not a Catholic because I was never raised as a Catholic. I was baptised Catholic and my surviving grandparents are Catholic (my paternal grandmother especially), but my parents eventually left because of my mother’s differing views (though it was for a moral reason in her eyes, she believed that if she stayed, she’d be a liar and a hypocrite).
Now, I go to a Protestant (United Methodist in particular, but I don’t identify) church with my family. When I’m older, I do plan to view the various ancient churches at least for a good look, and I’m aware of the theological standards to go by in some of these. I’ve only been to one Catholic Mass in my life, and this was years ago when I was seven or eight, and I didn’t understand a thing.
However, I do believe in what I profess, though I’m curious. God is patient.
