“the doctrines of the Catholic Church.”
Let me guess. You don’t believe in organisational churches, because you yourself have got it right and they have it wrong.
I’m sure you pray in secret before God every night, which is why you are here telling us about it?
Christ is very clear. Christians are to be brothers and sisters to one another because we CANNOT do it ALONE!
So good luck with your ‘church’ of one.
