In reference to the Eucharist as a sacrifice, Communion under both kinds belongs at least to the integrity and essence, of the rite, and may not be omitted without violating the precept of Christ: "Do this in remembrance of me" (Luke 22:19).
This meant that all who approached the altar were to be as pure as possible, and inevitably led to the exclusion of the laity from receiving the Eucharist under both kinds, reserving the practice to the clergy.
It is difficult to say when the practice of offering the chalice to the people stopped, but it seems to have been part of the way in which Church authorities sought to prevent anything disrespectful happening to the Eucharist; it was also, by this time, that the host (the Communion bread) was given only on the tongue.
[1]} This practice was challenged by the Bohemian reformer, Jacob of Mies, who in 1414 began to offer Communion under both kinds to his congregation in the Church of St. Martin in the Wall.
[4] This became the most emblematic issue of the Hussite Wars, which resulted in the permission of the communion under both kinds for Utraquists in Bohemia in 1433 (it would be banned again in 1627 and allowed again by the Patent of Toleration in 1781).
In the following century, this was challenged again by the Protestant Reformers, including Martin Luther, John Calvin and Huldrych Zwingli.
When the faithful come forward to receive Communion, they cross their hands over their chest, and the priest gives them both the Body and Blood of Christ from the chalice, using a spoon.
In this manner, everyone receives in both kinds, but no one takes either the consecrated Bread or the Chalice in their hands, thus reducing the possibility of crumbs accidentally being dropped or any of the Blood of Christ being spilt on the floor.
He then pours a small amount of unconsecrated red wine into the chalice which softens the dried particle as he hears the sick person's confession.
And in order that no one may be able to cavil at these words, and explain them as referring to the clergy alone, Paul informs us that the entire church at Corinth received the sacrament in both kinds.
It was therefore improper to coerce and oppress the conscience of those who wished to receive the sacrament agreeably to the appointment of Christ, and compel them to violate the institution of our Lord.
[7]The Eucharist is administered by a Lutheran priest under both kinds, often at the chancel rails or in a communion line, after hosts and a common chalice are consecrated.
"[8][9] In Anglican and Methodist liturgy, the bread (typically in wafer form) is administered by licensed clergy into the cupped hands of the communicant, usually kneeling at the altar rail.
[10] Communion under both kinds for the whole congregation was a central issue for the Protestant reformers, since they believed that it had been specifically commanded by Jesus at the Last Supper.
[5] John Calvin in his seminal 1536 work, Institutes of the Christian Religion, wrote; 'For Christ not only gave the cup, but appointed that the apostles should do so in future.
"[12] As a result of this revelation and anti-alcohol sentiment, the common practice of the Church of Jesus Christ of Latter-day Saints since the early 20th century has been to use bread and water and not to involve wine or grape juice.
