Calvary is the inner sanctum, where jesus poured out his blood on the mercy seat.
Um, there is not a single scripture that says that. The real Ark of the Covenant is and was even then, in Heaven:
Heb 8:1 Now of the things which we have spoken this is the sum: We have
such an high priest, who is set on the right hand of the throne of the Majesty in the heavens;
Heb 8:2
A minister of the sanctuary, and of the true tabernacle, which the Lord pitched, and not man.
Heb_8:5 Who serve unto the example and shadow
of heavenly things, as Moses was admonished of God when he was about to make the tabernacle: for, See, saith he, that thou make all things according to the pattern shewed to thee in the mount.
Rev 11:19 And the temple of God was opened in heaven, and there was seen
in his temple the ark of his testament: and there were lightnings, and voices, and thunderings, and an earthquake, and great hail.
Rev 15:5 And after that I looked, and, behold,
the temple of the tabernacle of the testimony in heaven was opened:
The copy of the ark on earth was buried in the days of Jeremiah, and hasn't been seen since.
The Ark of the Covenant and High Priest is required on the Day of Atonement, neither of which were at Calvary.
Passover doesn't require the Ark, nor Mercy Seat.
Also, one is fall (Atonement) and the other spring (Passover) feast.
