The aim of the Christian is to attain the blessed state of deiﬁcation. Deiﬁcation is identical with `likeness’, that is, to be like God. However, in order to reach the likeness, to attain the vision of God, and for this vision not to be a consuming ﬁre but a life-giving light, puriﬁcation must previously have taken place. This puriﬁcation and healing is the Church’s work. When the Christian participates in worship without undergoing life-giving puriﬁcation – and moreover these acts of worship also aim towards man’s puriﬁcation – then he is not really living within the Church. Christianity without puriﬁcation is utopia.
This purification is in fact our cleansing from hate to attain love because God is love. This is the aim of the commandments to teach us how to love.
Beloved, we are God’s children now, and what we will be has not yet appeared; but we know that when He appears we shall be like Him, because we shall see Him as He is.
