Heidelberg Q75

How art thou admonished and assured in the Lord's supper, that thou art a partaker of that one sacrifice of Christ, accomplished on the cross, and of all his benefits? Thus: That Christ has commanded me and all believers, to eat of this broken bread, and to drink of this cup, in remembrance of him, adding these promises: first, that his body was offered and broken on the cross for me, and his blood shed for me, as certainly as I see with my eyes, the bread of the Lord broken for me, and the cup communicated to me; and further, that he feeds and nourishes my soul to everlasting life, with his crucified body and shed blood, as assuredly as I receive from the hands of the minister, and taste with my mouth the bread and cup of the Lord.
