5. And on this account that,
which, the parts that beget being bridled by modesty, is most
chiefly and properly to be called Continence, is violated by no
transgression, if the higher Continence, concerning which we have
been some time speaking, be preserved in the heart. For this reason
the Lord, after He had said, “For from the heart go forth evil
thoughts,” then went on to add what it is that belongs to evil
thoughts, “murders, adulteries,” and the rest. He spake not of
all; but, having named certain by way of instance, He taught that
we are to understand others also. Of which there is no one that can
take place, unless an evil thought have gone before, whereby that
is prepared within which is done without, and going forth out of
the mouth of the heart already defiles the man, although, through
no power being granted, it be not done without by means of the
members of the body. When therefore a door of Continence hath been
set in the mouth of the heart, whence go out all that defile the
man, if nothing such be permitted to go out thence, there followeth
a purity, wherein now the conscience may rejoice; although there be
not as yet that perfection, wherein Continence shall not strive
with vice. But now, so long as “the flesh lusteth against the
spirit, and the spirit against the flesh,”18181818 it is enough for us not to consent
unto the evils which we feel in us. But, when that consent takes
place, then there goeth out of the mouth of the heart what defileth
the man. But when through Continence consent is withheld, the evil
of the lust of the flesh, against which the lust of the spirit
fights, is not suffered to harm.
