I think we agree, but I am troubled by the first statement quoted above. It is not a source of God's grace. That is the RCC position and is wholly necessary for them to purport to "control" the "means" of grace.
It is rather a testimony to or, as you put it, a sign of God's grace, but no more.
Similarly, the Lords' Supper is a remembrance -- no more. "Do this in remembrance of me ...."
"There are almost as many sects and beliefs as there are heads; this one will not admit Baptism; that one rejects the Sacrament of the altar; another places another world between the present one and the day of judgement; some teach that Jesus Christ is not God. There is not an individual, however clownish he may be, who does not claim to be inspired by the Holy Ghost, and who does not put forth as prophecies his ravings and dreams."-Martin Luther

Amen and to God be the glory.
Sacraments were instituted by Christ to be signs of His presence.In obedience we participate in the sacraments that were instituted given us by Christ .Baptism and the Lords Supper.
Those are special moments where Gods Grace is so real to us
The grace isnt in the ritual,but in meeting Christ there,in obedience to His word..
