Bread of Heaven

How perfectly formed the ritual of the celebrant's communion is in the Classical Roman Liturgy. It centres around the word Lord - which, of course, whether in the English or the Greek (Kurios) or the Latin (Dominus) stands for YHWH, the ancient unspeakable Covenant Name of the God of Israel. I genuflect in adoration saying that I will receive the Bread of Heaven and call upon the Name of YHWH; the wonder of which breaks me down into a threefold cry of unworthiness: YHWH, I am not worthy that thou shouldest come under my roof but only say the word and my anima, my breath, my life, my being, will be healed. Because at Mass YHWH comes under the Roof of the Temple building in which we stand; the One who entered the Temple at Jerusalem in his Name or his Glory is among us as a Man, as flesh and blood, as an epiphenomenon of the world he has himself created. More than that, the flesh and blood which is YHWH will become one with my flesh and blood so that I become the Roof of God. What can I give YHWH as a thank-offering for such a marvel? I, who am nothing, am yet everything only because of him and the thank-offering which I can give him is unceasingly his own gift to me: I will take the Cup of Salvation and again invoke YHWH, secure in the knowledge that I shall be saved from my enemies.
