I can understand your frustration, but what I can’t understand is your fear of becoming a heretic. If you are strong in your Catholic faith, that is not likely to happen. We are exposed to blatant sin every single day of our lives from the media, our permissive culture, materialism, the drug culture, etc., yet we choose to remain seperated from the world and remain Christians. That is how it has been for Christians from the beginning. Surely you are capable of not being affected by some liturgical abuses.
I don’t know how often these abuses really occur where you live, I have not seen anything like it in my area, but I have been to Masses in another area where there was liturgical dance and the priest added some of his own words to the prayers, which I found distasteful, but it didn’t affect my faith at all. Are you exposed to clown Masses weekly, daily, or what? Is there not another church in your area you can drive to?
Disobedience to one’s Bishop and the Pope is a serious matter, and is probably more likely to lead to heresy and schism than an occassional Mass with some abuses. Disobedience often takes on a life of it’s own, and is very easy to perpetuate in our lives. It is the very stuff schism and heresy is made of, and one of Satan’s tools to divide the Church. We should not participate in it, even if the other party does.
One’s love of God and reverence toward Him is not totally dependent on the circumstances of the Liturgy. It is an attitude of the heart and the humility to be submissive and be obedient to Him, and the onus is on you to nuture and develop that, with the help of the Holy Spirit. I don’t mean to offend you, but the ball is in your court here–you have the choice to remain a fully committed Catholic Christian, even in the most trying of circumstances. Whether or not our souls are damned is up to us, not the Liturgy we attend. God bless you.
