The challenge of the contemporary catechesis as it is approached by the patristic theology is extremely important: The Triads of Saint Gregory Palamas suggest a vivid theology which cannot go without the hesychast experiences, results of the ascetical life. The unity of the theological knowledge is represented, in fact, by the unity of the hesychast living on its whole. The knowledge of God is a unitary act, which moves from multiplicity to unity, not by acquiring multiplicity, but overcoming it in a transcendental way. Saint Gregory Palamas is categorical in this sense: the human judgment can stray from its verticality and congruency with its simple truths. The demand of establishing any kind of catechesis on answers regarding firstly the scientific primary truth `area` and, then, the truths resulted from the confessional knowledge is a premise which cannot form the base of a real catechetical itinerary.
