The Eucharist is indeed a memorial as is explained in the Catechism of the Catholic Church:
The sacrificial memorial of Christ and of his Body, the Church
1362 The Eucharist is the memorial of Christ's Passover, the making present and the sacramental offering of his unique sacrifice, in the liturgy of the Church which is his Body. In all the Eucharistic Prayers we find after the words of institution a prayer called the anamnesis or memorial.
1363 In the sense of Sacred Scripture the memorial is not merely the recollection of past events but the proclamation of the mighty works wrought by God for men.184 In the liturgical celebration of these events, they become in a certain way present and real. This is how Israel understands its liberation from Egypt: every time Passover is celebrated, the Exodus events are made present to the memory of believers so that they may conform their lives to them.
1364 In the New Testament, the memorial takes on new meaning. When the Church celebrates the Eucharist, she commemorates Christ's Passover, and it is made present the sacrifice Christ offered once for all on the cross remains ever present.185 "As often as the sacrifice of the Cross by which 'Christ our Pasch has been sacrificed' is celebrated on the altar, the work of our redemption is carried out."186
1365 Because it is the memorial of Christ's Passover, the Eucharist is also a sacrifice. The sacrificial character of the Eucharist is manifested in the very words of institution: "This is my body which is given for you" and "This cup which is poured out for you is the New Covenant in my blood."187 In the Eucharist Christ gives us the very body which he gave up for us on the cross, the very blood which he "poured out for many for the forgiveness of sins."188
1366 The Eucharist is thus a sacrifice because it re-presents (makes present) the sacrifice of the cross, because it is its memorial and because it applies its fruit:

Jesus, as quoted in 1365 of the Catholic Catechism above, says "This is my Body" and tells the Apostles to "Do this." What does a priest do? He breaks and blesses the bread, says the words of consecration as Jesus commanded, and distributes the Body of Our Lord to the people.
It sounds like you were not paying attention to the homilies, I know I was not when I was young. I mean I heard, but was not really "listening." Priests do a good job at driving points of the Gospel home in their homilies. Of course it is an impossible task to reach or satisfy every person, people of different ages and backgrounds. Try not to get hung up on disciplines or practices within the Church such as language or priestly celibacy. These are debatable topics and our not part of the spiritual teaching of the Church. For example, the Catholic Church translated the Bible into Latin because Latin was the common language of the people in Europe. Thus the Latin "Vulgate" from the word "vulgar," meaning common. Latin morphed into many other languages over the centuries and Catholics made translations of Biblical text into numerous common languages. But Latin was the universal language for most of Christianity. Latin was mandatory in high school for my older brother, but because of the Vatican II changes it was not required when I got there. If you didn't care to learn Latin you could read along in the missal. Latin was the common language of the people, and it is was a huge task to accurately translate the liturgy into many common languages. How much or into how many languages to translate the Bible or the liturgy is debatable. Let me ask, do you think poorly of Jesus because he spoke Aramaic but did not make copies of the Hebrew language Scriptures in Aramaic? How about the Apostles? Do you criticize them because they did not make Aramaic copies either? The liturgy is indeed ancient, so much of the liturgy is from the Bible, particularly Revelation. There is no need to make radical changes to what was passed down from Jesus through the Apostles. The Church is teaching the true Word of God. The priesthood of Aaron pre-figured the priesthood of Melchizedek. Melchizidek offered mere bread and wine, prefiguring Jesus who offers His Body and Blood.
John 6:48-58
48 I am the bread of life. 49 Your fathers ate the manna in the wilderness, and they died. 50 This is the bread which comes down from heaven, that a man may eat of it and not die. 51 I am the living bread[
c] which came down from heaven; if any one eats of this bread, he will live for ever; and the bread which I shall give for the life of the world is my flesh.”
52 The Jews then disputed among themselves, saying, “How can this man give us his flesh to eat?”[
d] 53 So Jesus said to them, “Truly, truly, I say to you, unless you eat the flesh of the Son of man and drink his blood, you have no life in you; 54 he who eats my flesh and drinks my blood has eternal life, and I will raise him up at the last day. 55 For my flesh is food indeed, and my blood is drink indeed. 56 He who eats my flesh and drinks my blood abides in me, and I in him. 57 As the living Father sent me, and I live because of the Father, so he who eats me will live because of me. 58 This is the bread which came down from heaven, not such as the fathers ate and died; he who eats this bread will live for ever.” RSVCE
