There is no more difficult task than to explain spiritual things to men
who think and judge only sensually. St. John Chrysostom says: "A soul
which is given over to passions cannot achieve anything great and noble,
for it suffers from a grievous blindness, like that of eyes darkened by
the flow of pus." Usually the most sensual men inquire about the
greatest divine mysteries. They do not inquire about that in order to
know how they can be saved, but rather to confuse the faithful and to
ridicule the Faith, and to justify their own sinful and passionate life.
Unable to raise themselves to the first rung of the heavenly ladder,
they fantasize about the last rung. Brethren, when such as these inquire
about the profoundest mysteries of the regeneration of the soul and the
Kingdom of Heaven, ask them, first of all, to fulfill the ten basic
commandments of God. If they do this, then their souls will be opened to
the understanding of the Divine Mysteries, inasmuch as that
understanding is necessary for the cleansing of their sins and passions,
and for eternal salvation.
