In Luther's Small Catechism, he states concerning the unbiblical Holy Communion...
Q. What good does this eating and drinking do?
A. These words tell us: "Given for you" and "Shed for you to forgive sins." Namely, that the forgiveness of sins, life and salvation are given to us through these words in the sacrament. Because, where sins are forgiven, there is life and salvation as well.

Luther is teaching Catholic heresy. Salvation is not obtained by quoting “these words in the sacrament.” A person cannot have their sins forgiven through partaking of Holy Mass or Holy Communion, which Lutherans and Catholics believe. In fact, the terms “Holy Mass” and “Holy Communion” aren't even found in the Bible. The Bible teaches the “Lord's supper” in 1st Corinthians 11:20. Also, the term “sacrament” is not found anywhere in the Scriptures. It is manmade tradition, originating in Roman Catholicism. The Lord's Supper, Biblically, is simply a time for a church (local gathering of believers) to REMEMBER the Lord's broken body and shed blood for our sins (Luke 22:19; 1st Corinthians 11:24-25).
Biblically, salvation happens the very moment that a person believes on the name of Jesus Christ to forgive their sins (Acts 10:43; John 20:31). There are no required church Sacraments nor rituals required for salvation as Lutherans and Catholics claim. Salvation is of the heart (Romans 10:10).
The Lord's Supper is an ordinance started by the Lord Jesus. It is not a Sacrament, nor does it have any special power to it. Their is no grace bestowed as most Protestants believe. There is no efficacy (power) in partaking of the Lord's Supper. The monstrosity of the Holy Eucharist which Roman Catholics teach and practice, called transubstantiation, where Catholics literally think they are eating Jesus' body and drinking His blood, is of the Devil.
Lutherans teach and practice a similar heresy called, consubstantiation, where they believe that a special grace is bestowed upon those who partake of Holy Communion. And as you have read, Luther taught that the Holy Communion brings salvation. The Bible does NOT teach any such thing as Mr. Luther claims. The Catholic and Lutheran views of Holy Communion are of the Devil. The Bible simply teaches that the Lord's Supper is a time of REMEMBRANCE in the church, a time when all the gears stop turning to think about how precious the Lord's bodily and blood sacrifice mean to us. It is a time of reflection, honoring our Lord for His sacrifice for our sins.
This is quite different than the bizarre and cannibalistic teaching of Catholics that they are literally consuming the Lord's body and blood into their digestive system, thus renewing them with spiritual life. Nor does the Bible teach anything near what Lutherans and Martin Luther claim, that is, that salvation is obtained through Holy Communion. Protestantism is rooted in the teaching of Sacraments, which the Bible does not teach. Water Baptism and the Lord's Supper are simply ordinances to be obeyed by believers who love the Lord and desire to please Him; but they are not mandatory for salvation, clearly evidenced by the plain teaching of the Scriptures.
Salvation is coming to God the Father in the name of Christ to be forgiven of one's sins (John 14:6). Jesus Christ is the key to salvation. Do you believe that He is the Christ, the Son of God, and will you receive Him personally as YOUR Savior, Who dies for YOUR sins? Christ died, that's history; Christ's died for me, that's salvation.
