There are seven church sacraments in Christianity. All of them provide beneficial benefits for the soul and body of a person, contribute to the growth of personality in a spiritual sense. The sacrament of the sacrament is the center of the liturgical life of the Church. It is necessary for every person who considers himself a Christian.
The sacrament of the sacrament was established by the Lord Jesus Christ Himself on Great Thursday before the crucifixion. During the Last Supper in one upper room, the Lord broke bread, blessed it, saying that it was the Body of the Son of God. Then he blessed the cup with the words that it was His blood. The Lord commanded to do this in remembrance of Him.
To this day, the sacrament is the main moment in the worship of the divine liturgy. The whole essence of the sacrament lies in the fact that, under the guise of bread and wine, believers partake (taste) the real body and blood of the Savior Himself. It turns out that an Orthodox person unites with his God. The Christian is sanctified and made holy. That is why it is important to be well prepared for the sacrament. If we consider that the main meaning of the life of an Orthodox person is the desire to achieve holiness, then the reason for the communion of believers with the holy mysteries is clear. It is in the sacrament that oneness with God is achieved. Then, in later life, grace departs from a person, to the extent of his sins. But one should not despair - it is necessary to strive again for perfection and proceed to the holy sacrament.
In addition to the fact that the reason for the communion of the holy mysteries is the striving for unity with God (holiness), the words of Christ Himself can be noted. The Lord says that a person who does not partake of the holy mysteries will not have life in him. That is, for growth in spiritual life, the sacrament is simply necessary. It is impossible to consider yourself a Christian and be outside the fence of the Church. Christ is the head of the Church, therefore those who do not partake of Him in the holy sacrament cannot take part in the grace-filled church gifts.
An Orthodox person also takes communion in order to reach paradise after death. It is simply impossible for a Christian to be with God after death, if during his lifetime the Orthodox was not with the Lord.
It should be noted that all the reasons for communion of the holy mysteries of Christ have in themselves a single goal - striving for God, receiving grace and the hope of eternal life with Christ after death.
