Only Jesus can save. Not the church, not any ceremonies.
If you are trusting in the church to save you, I suppose God will let you appeal to that, but it's not going to do you any good. It's Jesus only and Jesus alone.
The church is not Jesus Himself. It's the bride of Christ, the body of believers of all time and places. It's what become part of when you believe, not what you join to be saved.
You can't say you weren't warned.
The Catholic Chruch has sacraments, not "ceremonies" and they, the sacraments, are given us by Jesus. So yes, only Jesus can save, and he gave us the Church of the Living God so that we know how.
