Finally, we receive the Sacred Body and Precious Blood of the God-Man meant for our nourishment on the difficult path to Paradise. Undoubtedly, Jesus is with us during Mass. The Madonna is present during each Mass. And here's how. Therefore, each Mass is the renewal of what Christ did on Holy Thursday in the Upper Room and the next day on Good Friday atop Calvary.
Any sacrifice has both an internal and external dimension.
Simply put, the internal aspect is the interior disposition that is tangibly expressed by the external aspect. But she is the one from whom He received the very Flesh and Blood that becomes present on our altars. . . . She is also united with the interior dispositions of her Son. Just as He, in the glory of Heaven, still renews the offering of His obedience, His willingness to die again, were the Father to ask that, so too she has not changed the disposition of her Heart. She once consented to His offering at tremendous cost to herself.
