No, I say it cannot be any of the above without adding to Torah. And adding to (or taking from) Torah is sin. It is a simple thing.
Semantics, I say. Jesus instituted Baptism and the Commemoration of the bread and wine, which I trust you are not denying?
You need to define "sacrament" and then defend that, much as one who attacks or defends "evolution" must define the term first.
I agree with your intention, but don't understand the point you are making. Jesus gave us a new command (John 13:34) to go with the new covenant (Matt 26:28)
1. What is a "sacrament" in your mind, the RC definition as posted in the Council of Trent?
2. How does that relate to "adding" to the Torah?
