for Christians, Jesus is our Sabbath. We rest in Him and His sacrifice on the Cross. We don’t observe ceremonial laws of the OT, which were types and shadows pointing towards Jesus Christ.

Sure. The RCC just made up its own and substitutes them for the OT Law. So it can perhaps legitimately claim that it's not based on having to obey the Law that God established, but instead demands that its adherents obey the law IT established.

Not a good trade off.

If the OT Law that God Himself established can't save, then nothing man substitutes for it can save either.

[one Lord one faith one baptism]

“then nothing man substitutes for it can save either”

When that man is Jesus Christ, it can.

that’s the difference between what Christians and non-Christians believe.
