Lovers can have between themselves a depth of intimacy and communication that goes beyond words. To think that communication with the Living God, our Abba, cannot involve something equivalent or even greater is ridiculous (Psa 42:7).
The prayer “Our Father” raises those who make themselves familiar with it to that prayer of fire which very few know from experience. It is an ineffable state that is far above all human feeling, without the sound of any voice, without any movement of the tongue, without any articulate word. The soul is wholly filled with light and no longer makes use of human language, which is always limited. But it engrosses the whole person and becomes an abundant spring from which prayer flows and soars in an ineffable fashion up to God. It says so many things in this brief space of time that it cannot easily express them or even remember them (IX, 25).
This fullness, however, does not do away with the intellect, rather it fertilizes it. The spirituality of the Fathers is not anti-intellectual. For the human being is … capable of sound reasoning. The more the intellect is imbued with the light and love of God, the more it is purified, refined, broadened, and cognisant of conscientious and beautiful thoughts (p. 209).
