Yes, these, too. The sacraments save because they are visible vehicles of invisible grace, voluntarily received. The discipline surrounding the sacraments -- the Laws of the Church --do not save. They tell you when you endanger your soul by straying too far from the community of Christian faith; they are useful but not salvific. Circumcision was useful as well, by the way.
Infant baptism is not a discipline of the Church, strictly speaking (people get baptized when they or their sponsors are ready for the committment), but other things that you mentioned are.
Roman Catholism is Judaism redux
Roman Catholism is Judaism fulfilled. We are the Heavenly Jerusalem today. Our priests are true priests in the order of Melchisedek. We build the true temple after the Mosaic model, and we could do it because grace was given us.
When one says "You are saved by grace, BUT..."
The Church does not say any "but". We are saved by grace alone, period. Other things, faith and works, are the consequence of it (Eth 2:8-10). It is the Protestant heresy to add "sola fide" to the divinelty proclaimed gospel of "sole gracia", and twist St. Paul's words in the process.
I believe that the council of Jerusalem and galatians condemns Judaizers...The Old Covenant belongs to the Jews..the New Covenant is with the saved, be they jew or gentile.. ...God destroyed the temple and the priesthood ...no more sacrifices , no more vestments.. no more altars ....
Jesus indeed fulfilled the OT, a church does not.. We are to seek Christ and kneel before the Savior.. Not the pope or bishops ...One day every knee will bow and tongue profess that Jesus is Lord..not a man made church or man made pope.. as Peter said..Stand up , I am just a man like you
There is no priesthood, no papacy , no apostolic succession in the NT church as found in the scriptures.. it is all made up by the whims of men..
Christ was the last priest, He was the last sacrifice.. he is the rock the church is built on .. Solus Christus or ("Christ alone" or "through Christ alone"), Soli Deo gloria ("glory to God alone")
