The finished work of Christ is referring to his finished work of redemption when he offered his own blood on the altar in heaven.
11Day after day every priest stands and performs his religious duties; again and again he offers the same sacrifices, which can never take away sins. 12But when this priest had offered for all time one sacrifice for sins, he sat down at the right hand of God... Hebrewds 10:11-12
That work is done. Finished. Completed. Unlike the long succession of Levitical priests who had to continually offer new sacrifices, their work never being done, because their ministry and sacrifice did not last and could not complete anything. There was always another sacrifice to be made. But Christ, on the other hand, is not busy continually being re-sacrificed. That work is DONE. It got done one time for all time for all people. Now what happens is many appeals go out to the one and only finished Sacrifice, always there in heaven before the Father ready to complete a redemptive work for another soul on earth who will put their faith in it.
Offering of the liturgy!
The holy sacrifice of Jesus Christ!
Luke 22:19 “do this in memory of me”!
The Passover
(The new covenant Passover sacrifice of Christ)
“It is finished” not the redemptive work of Christ but the Passover sacrifice!
The cup refers to the Passover
The sacrifice prefigured the sacrifice of Christ
Christ was celebrating the Passover and changing it into the new covenant Passover in his own body and blood
Began in the last supper with the psalm then to the garden and ended with his death in the cross with the words commanded to be said at the consummation of the Passover sacrifice by the high priest “IT IS FINISHED”!!!
jn 1:29 The next day John seeth Jesus coming unto him, and saith, Behold the Lamb of God, which taketh away the sin of the world.
1 cor 10:16 The cup of blessing which we bless, is it not the communion of the blood of Christ? The bread which we break, is it not the communion of the body of Christ?
1 cor 11:23 For I have received of the Lord that which also I delivered unto you, that the Lord Jesus the same night in which he was betrayed took bread:
24 And when he had given thanks, he brake it, and said, Take, eat: this is my body, which is broken for you: this do in remembrance of me.
25 After the same manner also he took the cup, when he had supped, saying, this cup is the new testament in my blood: this do ye, as oft as ye drink it, in remembrance of me.
26 For as often as ye eat this bread, and drink this cup, ye do shew the Lord's death till he come.
Notice the connection to his betrayal and death
1 cor 5:6-8
For even Christ our passover is sacrificed for us: Therefore let us keep the feast
So

So the it in “it is finished” is not the work of redemption but the Passover sacrifice!
but something is missing we have to eat the lamb
jn 6:53 Then Jesus said unto them, Verily, verily, I say unto you, Except ye eat the flesh of the Son of man, and drink his blood, ye have no life in you.
54 Whoso eateth my flesh, and drinketh my blood, hath eternal life; and I will raise him up at the last day.
55 For my flesh is meat indeed, and my blood is drink indeed.
56 He that eateth my flesh, and drinketh my blood, dwelleth in me, and I in him.
57 As the living Father hath sent me, and I live by the Father: so he that eateth me, even he shall live by me.
“It is finished” the Passover sacrifice!
Consummation of the new Passover or the beginning of the new and eternal covenant!
