Not necessary for salvation, MarMema. Not needed. Misleading. Faith is what saves you; the Commandments we can't follow. For if we all had sufficient faith we could. You won't get it in the Church. You and I may find it if we are lucky -- in ourselves, but I am far from it. And the Church is doing nothing for me to reach it.
When you attend liturgy once a year you mean?
And how does this work with your tagline which says the church is pure Christianity?
God's Mercy is "what" saves us, Kosta.
