If I convert to Catholicism, move back to my hometown (where there is no Catholic church within 50+ miles), and attend the church I grew up in, that my parents pastor, is this supporting heresy? Will I be sinning?
First, it is a bad idea for a Catholic to live that far from the nearest Catholic Church. You should seriously consider living nearer to it.
Of course the answer to your question depends partly on whether you mean you will be driving 100 miles to get to Mass and back and
then attending the service in your parents’ church, or whether you mean to skip Mass and go to your parents’ church instead. If it is the latter, missing Mass is still a mortal sin, and going to a protestant church does not make it better.
If you are intending to go to both Mass and your parents’ service, that is probaby not sinful as long as you don’t support the church financially. Whether it is a good idea is another question. Your parents would probably prefer you to stay in their denomination. If you go to their church often, you are either setting yourself up to leave the Catholic Church, or you are holding out false hope to your parents. Neither option is a good idea.
If I go hear Lisa Bevere speak when she visits a womens conference, would that be sinning?
Probably not. I don’t know anything about her and her website apparently doesn’t work with Firefox. As long as she’s not actually anti-Catholic, it should be OK.
I’m just a little confused - I didn’t realize that every aspect of a person’s doctrine had to line up with the Church’s - I assumed that would rule out the vast majority of ALL teachers, Protestant or otherwise. Did I misinterpret something?
It depends on what you mean by “the person.” If the person you mean is yourself, then yes every aspect of your doctrine has to line up with the Church’s.
If the person you mean is someone whom you are supporting financially through contributions, and that person is teaching about religion, then it may well be sinful if they are teaching things that are against the Catholic faith. If you are not supporting them financially, I don’t personally think it is sinful, but I think it is REALLY REALLY unwise. When you are new to the faith, it is hard to know enough to know which teachings are against the Church and which aren’t. It is a lot safer, at least for a couple of years, to get grounded in Catholicism first before spending a lot of time listening to Protestant teaching. EWTN is really good. I’ve never heard anything on it that was at all contrary to the Church’s teachings. There are a lot of speakers out there that are faithful Catholics. The general idea is that as a Catholic, you would get your teaching from Catholics.
But OTOH if you are just talking about general motivational speakers, or classroom instructors in non-religious subjects, or anything like that, they can be any religion.
Anyway, that is how I see it, but I am not an expert.
God bless you on your journey!
