(You may reject that label all day long, but in the eyes of the Church you still are one)
While I certainly agree, in the universal sense of the word (catholic).
I am under anathema, according to Trent for all the denials i maintain in regards to the Papacy, the Marian dogmas, the eucharist, etc...
I guess that would make me an apostate or heritical Catholic in the eyes of Rome.
Unless you have gone through a hearing after filling out loads of paperwork............you are still a Catholic.
You will come back, and we welcome you back at any time. Sit down with a priest and get your questions answered.
Also, there may be a class in your area — you didn’t say where you are from on your profile page — for returning Catholics.
With all the rebellion about same-sex marriages, homosexual bishops, etc. I’m surprised that you have not come back to the One Holy Catholic and Apostolic Church already.
I only think you would be regarded as an apostate if you rejected the Triune God. (for example if you became an atheist, a Muslim, a Jehovah's Witness, or something along those lines)
As far as a heretic...yeah, maybe. Canon 751 defines Heresy as: "...the obstinate denial or obstinate doubt after the reception of baptism of some truth which is to be believed by divine and Catholic faith;"
The tough word in there is "obstinate"
The New Commentary on Canon Law says that you must have "male fide" (bad faith) and you must do so with "full knowledge" to be really guilty of heresy. In other words, you have to believe that it is true and reject it anyway.
That is not to say that you don't hold heretical beliefs. But for you to be guilty latae sententiae of the crime of heresy, you would basically need to be intentionally leading somebody (to include yourself) astray, knowing that you are leading somebody astray from the truth. I, frankly, don't believe that most fallen-away Catholics are in that position (some are...but those are by far and away the minority).
Having said that, I think it makes some ex-Catholics feel really good to believe that they have personally been anathematized by the Church and that they were thrown out on their ear and condemned to everlasting flames of doom...and if it makes you feel good, please, by all means, carry on.
