There are no greatest. Everything is equal in God's eyes.
The sacraments at the Service of Communion is from the Catechism, the header for Chapter Three of Part Two: Question 1533 names Baptism, Confirmation, and Eucharist as the Sacraments of Initiation. In 1544 It mentions two other sacraments, Holy Orders and Matrimony directed towards the salvation of others. These five sacraments are "at the Service of Communion".
Sacraments are Holy Communion and Holy Baptism. Other Rites include Anointing of the sick, Confession, Confirmation, etc.
Communion is highly regarded in the Lutheran Church as a sacrament. It is rich with meaning and, with baptism, is considered one of the most important Christian blessings. Lutherans adhere to the ancient understanding of Holy Communion as a means of grace by which Jesus makes himself truly and spiritually present to the Church. The communicant accepts the true body and blood for food and drink for the forgiveness of sins. It is a blessing which bestows and signifies unity amongst Christians. The blessing or merit is not in the eating or drinking, but in the act of God "coming to us" through the physical, tangible earthly elements of bread and wine. Lutherans prepare for communion with prayer, confession and reconciliation, and sometimes fasting. The liturgy of the Lutheran Church is centered around two high points which are 1. the hearing of the Word (Law and Gospel) and 2. the sharing of the meal (Holy Communion.)
Two sacraments - Baptism and the Lord's Supper (Holy Communion)
Holy Orders and Matrimony are sacramental acts that are often combined with a celebration of the Eucharist (Communion). The Eucharist, however, is separate from those two rites.
The holy water and candles would be for the priest when he came to perform the Last Rites (confession Holy Communion, Apostolic Blessing, Anointing (Unction). Salt is usually used during an exorcism, and I have no earthly idea what the nails would be for, certainly no Catholic ritual.
Red is symbolic of two things: 1. The Holy Spirit (who appeared as tongues of flame on the disciples on Pentecost). 2. The Precious Blood of Jesus, which is received in the form of wine at Communion. Boys may wear a red sash at their First Holy Communion (so everyone can see it's their First Communion), but when they receive Communion on subsequent occasions, they just wear regular clothes.
Most Catholic children receive their First Holy Communion when they reach the age of reason, about seven years of age. Communion is the receiving of the body and blood of Christ that have been transformed from simple bread and wine at the consecration of the Mass. Children usually require one or two years of education about the sacrament before they receive communion for the first time.
-If you have committed a mortal sin and haven't gone to confession yet. -If you have not fasted enough. -If you aren't of the right age to receive Holy Communion. -If you don't believe in the real presence of Christ in the Eucharist.
Baptism and Holy Communion. But, Lutherans are not dogmatic about the number of sacraments. A sacrament is a rite, commanded by God Himself, in which He makes Himself especially present. It is taught that Holy Baptism an Holy Communion are sacraments. Often, Confession and Absolution is referred to as the "third sacrament." The other four rites ( confirmation, marriage, holy orders, anointing of the sick) are viewed as sacramental in nature, while not necessarily, or so clearly definable as, sacraments.
The Assemblies of God practices two ordinances: Water Baptism and Holy Communion. Water Baptism is by immersion after repenting of one's sins and receiving Christ's gift of salvation. Holy Communion (the Lord's Supper) is a symbolic remembrance of Christ's suffering and death for our salvation
