If blood (and in the blood is everything necessary for life) does not reach an organ, then after a certain period it dies; if juices do not reach a branch, and with them everything necessary for growth – the branch withers. Similarly for a member-organ of the Body of the Church the Eucharist – is the Blood of Life Hypostasis. Who drinks this Blood, lets it pulsate in himself, he is Alive in the Body (may be sick-sinful, but Alive!) (see Part I).
Communion of the Eucharist for Christians – is not something that can be done or not done – at will; it is a necessity and a duty. A person, who was born into the world (in phase II) to live (to survive), has no alternatives, no choice: to breathe oxygen or not to breathe! Eucharist for a Christian (baptized into the Body of the Church) – is a ontological necessity, a principled, natural, not customary obligation! Therefore, a Christian has no choice: to commune or not to commune the Eucharist (= to breathe or not to breathe?! to live or not to live?!) – only the Eucharist gives Life. Eucharist for a Christian – is everything: Food, Drink, Oxygen, etc. A person in phase II lives the rhythm: from inhaling oxygen to the next inhalation, from one eating of food to the next intake of food, from experiencing erotic communication-love with a wife (husband) to the next sacrificial meeting in a tender erotic-loving communication of spousal hypostases, etc. Similarly, in the Church a Christian lives the rhythm: from Eucharist to Eucharist, which for him is everything: Food, Drink, Oxygen, Eros…
The Eucharist – is the fullness of the Holy Spirit (see the rite of the Liturgy of John Chrysostom). Communion of this fullness of Divinity (Life of the Most Holy Trinity) takes place at the Eucharist, where it is present (becomes apparent) corporeally – under the guise of deified Bread and Wine, which, like “the burning bush” (compare Exodus 3, 2), burn with the Fire of Divinity, the Holy Spirit! The Spirit vivifies, and the flesh (body and blood, bread and wine) does not help! Therefore, Christians commune at the Eucharist not the body and blood, not bread and wine (from which there is no benefit, except for physiological nourishment from ordinary food: breakfast, lunch…), but the Holy Spirit under the guise of Bread and Wine, that is, communes the hypostasis by the Holy Spirit to the Divine Life (trinitarian mode of existence in kenotic humble love), and not nature eats something! Therefore, the Eucharist (= the Church) – is the fullness of Theanthropic Hypostatic Trinitarian Life, to which the Church joins by the Holy Spirit. The goal of life of every creature – to acquire the Holy Spirit – is achieved in the Eucharist, in the spiritual, that is, eucharistic life in the Body of Christ (in the Church).
Here is the full translation of the extensive text you provided:
“The Church is the School of Hypostatic Being, where we learn to be like God, that is, to be deified in the Grace of the Holy Spirit! Jesus Christ is the Teacher, and Christians are the disciples! The Eucharist is the lesson, the class, where the Teacher, through the Holy Spirit, teaches the disciples about Divine Life, teaching them to know the Father, to be children of God, to be one with the Trinity. Extracurricular time is the domain of asceticism—a period for assimilating the ‘material’ and skills acquired in the ‘lesson.’ Asceticism (practice in virtues, primarily humility and love, in what we have learned (to each their own measure) in the Eucharist, in the Kingdom of God—Humble, Sacrificial, Kenotic Love of God-the Trinity and the Saints) is the ‘homework’ that we must do (zealously perform, truly struggle with passions that prevent us from doing our ‘homework’) until the next ‘lesson’ (Eucharist) of Hypostatic Triune Life. Those who are in the School (baptized) but do not attend the Lessons (Eucharist), will be expelled from the students’ roll! Those who attend the Lessons but do not repeat after the Teacher what he shows (do not partake in the Eucharist), will know nothing (will not know how to Live) and will fail the exam (on Love). And those who repeat after the Teacher, take notes, listen (partake in the Eucharist) but do not do their homework and do not assimilate the material presented in the lesson (by zealously performing the gospel commandments and proper spiritual life), will not be able to enter life, become a citizen of the society of Saints, and will meet the fate of the former. (Every time we speak pedagogically about the ultimate unfortunate lot of someone, we must mentally add the words: UNTIL THEY REPENT! That is, they will exist in ‘such a state’ until they repent). In the following chapters and parts, we will try to talk more about how to do ‘homework’ and prepare for the next ‘lesson’ (i.e., how to assimilate the Eucharist and prepare for the next one).
The Lord says that where two or three are gathered in My name, there I am among them. These words are often cited by Protestants to affirm that they are in the Church. But those who think so do not know neither the Scripture nor the power of God! What does it mean ‘in My name’? In the first part, we talked about ‘to be baptized in someone’s name’ – it means to become the property of the one in whose name one was baptized, to begin to live not one’s own life, not to fulfill one’s own will, but to live the will of the owner (‘to hypostasize’ him). Therefore, to gather in the name of Christ = to gather in Christ (Jesus Christ is the Kingdom of God, the Church). And when are we in Christ? Then, when we are in Him, and He in us – and this is achieved when we consume Him in the Eucharist! Therefore, to gather in the name of Christ – is to gather at the Eucharist (in the context of spiritual, that is, Eucharistic life)!
