When a person, or religious organization, keeps inventing sacraments, then it is they're keeping of the sacraments they have faith in, not Christ. Otherwise, why keep those invented sacraments?
And when one goes to a confessional and tells a "priest" about their sins, then it is their going to the confessional and doing the confession ritual and penance that they have faith in, not Christ. Otherwise, why not go directly to God, from within the heart, through Christ for the forgiveness of sins as Christ taught?
Christ never taught anything about ritualistic sacraments, or going to confessionals. He taught faith. It is only the flesh, seeking to feel it has earned its spiritual relationship with God that comes up with the formulation "these are the things I do because of faith." Christ's teaching was that faith is not about man "doing." It is faith in what God has, and will, do.
Just so that everyone knows I'm not singling out the Catholics, it would be entirely possible to write exactly what I just wrote, only substituting the ritual and legalism details of any protestant denomination for the mass/ritualistic sacraments/confessional part, and the doctrinal point would be just as valid.
Christ did indeed teach that salvation and relationship with God is based on faith and only faith.
It is the Catholic Church that invented all the nonsense about Mary being a lifelong virgin, and that one prays to her to get healing, favors, and whatever. And it is the Catholic Church, which elects "saints", and says you can pray to them for special favors; isn't it? I don't remember Christ teaching anything about praying to Mary or "saints". And it is the catholic church that teaches that you can't be forgiven for sins without coming to its confessional booth, telling your sins to someone it calls a "priest" and doing whatever penance that "priest" tells them to do; right? That is the Catholic Church, isn't it? Or is the church that does all that stuff some other church and I just got confused for a second? This isn't a stereotype, it is just fact. Is the Catholic Church now teaching that one simply goes to God in personal prayer about sin and is forgiven based on the perfection and efficacy of Christ's work on the cross? If that's what they're teaching these days it would be the first I've heard about it.
If the rituals, ceremonies, legalisms, and taboos the Catholic Church started inventing in the middle of the first millennium are just a natural outgrowth of Christ's teaching (the expression of faith, if you will) then why would not the rituals and ceremonies and taboos and legalisms of any other church be the same? For instance, the day of Pentecost was shortly after Christ's death and resurrection and we are told people were speaking in tongues, etc. So why would it not be valid for Pentecostal churches to say: well, what we do goes all the way back to the days of Christ's ministry, death and resurrection, so when we "speak in tongues" it is simply a natural outgrowth of Christ's ministry and what early Christians did. Therefore, you can't be saved or have a relationship with God unless you join our church and do this "speaking in tongues" thing.
