In this work, using the example of the teachings of the Athonite elder Paisius, the general Christian foundations on which the relationship between husband and wife and between parents and children should stand were determined. In his teachings, Elder Paisios proceeds from ideas about the divinely ordained union of a man and a woman, the significance of the sacrament of Marriage for the formation of a family as a single organism, and the need for unified spirituality in the aspirations of a husband and wife. At the same time, tuning the spiritual life of spouses to the “frequency of God,” as the elder wrote, is achieved through living together in the Church and the mandatory acceptance of the Church Sacraments. The elder also gives a definition of a marriage union, which can be called true only if the union of the spouses occurs together with God, since marriage is a triple union, sealed by the love of a man, a woman and God.
