How do we define a Christian and why is that important? It would seem that the definition of Christian is ambiguous, having been watered down my countless denominations that continually redefine Christian theology. Why is this important? It is important to define what a Christian is because if we do not then anyone can call themselves a Christian and be misled or mislead others into incorrect teachings. It is important to define what a Christian or Christianity is so that people can know the truth. If we accept anyones profession that they are a Christian without having first investigated then we will be held accountable.
The easiest way is to contrast everything against the sacrament of sacraments, the Eucharist. In the Orthodox Church this sacrament is considered to be the Body and Blood of our Lord Jesus Christ, not as in the Catholic teaching of transubstantiation, but a mystical or spiritual transformation, not a transformation of substance. It is not considered symbolic at all in Orthodoxy. It is not considered symbolic by Christ in the Gospel of St John either, He says: "Very truly I tell you, unless you eat the flesh of the Son of Man and drink his blood, you have no life in you. Whoever eats my flesh and drinks my blood has eternal life, and I will raise them up at the last day. For my flesh is real food and my blood is real drink. Whoever eats my flesh and drinks my blood remains in me, and I in them. Just as the living Father sent me and I live because of the Father, so the one who feeds on me will live because of me. This is the bread that came down from heaven. Your ancestors ate manna and died, but whoever feeds on this bread will live forever.” He said this while teaching in the synagogue in Capernaum."
Christ does not say that this is symbolic in any way, He is literal, in fact when the people were grumbling He reiterated that He was being literal. This caused many to desert Christ, so why didn't He explain that He was only speaking symbolically? To further prove this point, when Christ instituted the Eucharist in Mt 26:26 He said: “Take, eat; this is My body.” Then He took the cup, and gave thanks, and gave it to them, saying, “Drink from it, all of you. For this is My blood of the new covenant, which is shed for many for the remission of sins." Notice that Christ does not once say that this is a symbol but that this is My Body and this is My Blood. He then refers to this as His blood of the new covenant which is shed for many for the remission of sins. This is literal, not symbolic in any way.
Christ says in John 6:53 that: "Most assuredly, I say to you, unless you eat the flesh of the Son of Man and drink His blood, you have no life in you. Whoever eats My flesh and drinks My blood has eternal life, and I will raise him up at the last day. For My flesh is food indeed,[h] and My blood is drink indeed. He who eats My flesh and drinks My blood abides in Me, and I in him." This again is clear in that we must partake of the Eucharist, which Christ instituted and said is His Body and His Blood. Christ says that unless we eat His flesh and drink His blood, we will have no life in us, meaning we cannot receive salvation unless we partake of the Eucharist.
So it stands to reason, whomever rejects the Eucharist rejects Christ and in turn rejects their own salvation. This we cannot consider to be Christian. Any denomination that either rejects the Eucharist or teaches that it is merely symbolic cannot be considered Christian. For any Orthodox to suggest that one who rejects the Eucharist is Christian is heresy because they are stating that a person who rejects Christ is in some way a Christian. This is in no way a condemnation of the people who may believe this as most probably do it out of ignorance. It is important for Orthodoxy to strictly define what it means to be Christian, and this is one way of doing that.
