Oh yeah, some Eucharist as Sacrifice quotes I culled from it:
On the Lord’s own day, assemble in common to break bread and offer thanks; but first confess your sins, so that your
sacrifice may be pure. However, no one quarreling with his brother may join your meeting until they are reconciled; your
sacrifice must not be defiled. For here we have the saying of the Lord: ‘In every place and time offer me a pure
sacrifice; for I am a mighty King, says the Lord; and my name spreads terror among the nations.’"
-Ch 14 (the Didache)
“Our sin will not be small if we eject from the episcopate those who blamelessly and holily have offered its
Sacrifices.” Source: Letter to the Corinthians, [44,4](Clement of Rome)
"God has therefore announced in advance that all the sacrifices
offered in His name, which Jesus Christ offered, that is, in the Eucharist of the Bread and of the Chalice, which are offered by us Christians in every part of the world, are pleasing to Him." “Dialogue with Trypho”, Ch. 117, circa 130-160 A.D.(St. Justin Martyr)
Moreover, as I said before, concerning the sacrifices which you at that time offered, God speaks through Malachias, one of the twelve, as follows: ‘I have no pleasure in you, says the Lord; and I will not accept your sacrifices from your hands; for from the rising of the sun until its setting, my name has been glorified among the gentiles; and in every place incense is offered to my name, and a clean offering: for great is my name among the gentiles, says the Lord; but you profane it.’ It is of the sacrifices
offered to Him in every place by us, the gentiles,
that is, of the Bread of the Eucharist and likewise of the cup of the Eucharist, that He speaks at that time; and He says that we glorify His name, while you profane it." -“Dialogue with Trypho”, (Justin Martyr)[41: 8-10]
(Note how the Fathers consistently interpreted that verse from Malachi! this verse is the one they’re talking about)
Malachi 1:11-12
Oh, that there were one among you who would shut the doors, that you might not kindle fire upon my altar in vain! I have no pleasure in you, says the LORD of hosts, and I will not accept an offering from your hand. For from the rising of the sun to its setting my name is great among the nations (Gentiles), and in every place incense (Dhouay Rheims - sacrifice) is offered to my name, and a pure offering; for my name is great among the nations, says the LORD of hosts. 12 But you profane it when you say that the LORD’s table is polluted, and the food for it may be despised.
“The priest who imitates that which Christ did, truly takes the place of Christ, and offers there in the Church a true and perfect
sacrifice to God the Father.”, Source: St. Cyprian wrote to the Ephesians circa 258 A.D:,
"‘Holy, holy, holy Lord Sabaoth, heaven and earth is full of Your glory.’ Heaven is full, and full is the earth with your magnificent glory, Lord of Virtues. Full also is this Sacrifice
, with your strength and your communion; for to You we offer this living
Sacrifice, this unbloody oblation.,-“The Sacramentary of Serapion,
Prayer of the Eucharistic Sacrifice” [13],
"I wish to add something that is plainly awe-inspiring, but do not be astonished or upset. This Sacrifice
, no matter who offers it, be it Peter or Paul, is always the same as that which Christ gave His disciples and which priests now offer: The offering of today is in no way inferior to that which Christ offered, because it is not men who sanctify the offering of today; it is the same Christ who sanctified His own. For just as the words which God spoke are the very same as those which the priest now speaks, so too the oblation is the very same."

"For the whole Church observes this practice which was handed down by the Fathers: that it prayers for those who have died in the communion of the Body and Blood of Christ, when they are commemorated in their own place in the sacrifice
itself; and the
sacrifice is offered also in memory of them on their behalf. Source: St. Augustine, Sermons 172,2, circa 400 A.DHave fun!
