Sacraments do not confer grace.
Grace comes through Jesus Christ.
John 1:14-17 And the Word became flesh and dwelt among us, and we have seen his glory, glory as of the only Son from the Father, full of grace and truth. (John bore witness about him, and cried out, “This was he of whom I said, ‘He who comes after me ranks before me, because he was before me.’”) For from his fullness we have all received, grace upon grace. For the law was given through Moses; grace and truth came through Jesus Christ.
Yup, grace comes from Christ through the Sacraments that He instituted.....like the Eucharist for example that you have given up.....
