Knox on Baptism

We utterly condemn the vanity of those who affirm the sacraments to be nothing else than naked and bare signs. No, we assuredly believe that by Baptism we are engrafted into Christ Jesus, to be made partakers of his righteousness, by which our sins are covered and remitted, and also that in the Supper rightly used, Christ Jesus is so joined with us that he becomes the very nourishment and food for our souls.

-John Knox, The Scots Confession, 1560
