"Not in addition to the one great sacrifice": A Hackney Phalanx sermon on the Sacrament, Good Friday, and Easter Day

From A Course of Sermons, for the Lord's Day throughout the Year, Volume I (1817) by Joseph Holden Pott - associated with the Hackney Phalanx - an extract from a sermon for Good Friday.  Here Pott appears to make reference to the custom of not celebrating the holy Sacrament on Good Friday, regarding this as a means of emphasising the commemoration of the Lord's sacrifice, for "our humble sacrifices of praise" (a reference to the Prayer of Oblation) are "not in addition to the one great sacrifice". And thus we offer eucharistic praise and thanksgivings -  "our bounden and perpetual duty" (again, echoing the Prayer Book Holy Communion) -  on Easter Day, amidst "the joy and triumph of our Redeemer's resurrection":

In a word, the whole history of our Redeemer's passion, this day recited in our ears, sets forth, at how great a price that violation of the sacred law and righteous government of God, and that fatal injury done to the noblest work of his creation, were to be repaired. It calls upon us with a voice, to which the dullest ear can scarcely be insensible, to acknowledge, with a deep humiliation, and embrace, with humble gratitude, the benefit so freely tendered, and procured for us at so vast a cost ... 

Happy is it for us, that the remembrance of our Lord's precious death, though it strike the soul with some sad thoughts, is coupled with a secret sense of joy and consolation. Our sadness cannot resemble that of the first desolate attendants on the cross of Christ. God hath spared us the drinking of that cup. The Christian cup, then, is the cup of gratitude and praise: yet before we touch it we must call to mind the depth, and consider the anguish of those wounds, by which it was replenished. Our thankfulness will then be full. We shall offer up our humble sacrifices of praise, not in addition to the one great sacrifice, which is alone sufficient to its ends and purposes, but as our bounden and perpetual duty. 

Such are the peculiar themes of this day's celebration; the main grounds, first of our humiliation, and then, of our sure comfort and rejoicing. The dawn follows the darkness: but we must first climb the barren top of Calvary, and stoop to look into the shadows of the sepulchre, before we can hope to witness, with fit dispositions, and due gratitude, the joy and triumph of our Redeemer's resurrection. 

Above all, let us remember, that the chief lesson which we have to gather, when the memory of our Redeemer's sufferings are set before us with a special celebration, consists in that conviction which we ought to entertain of the heinous quality of sin, which made so precious an atonement needful, in order that God might be just, and yet that he might justify the sinful, through the blood of Christ.
