CL 497, 499 - The Flesh and the Spirit

CL 497[2]

. . . the flesh is against the spirit,
which is to say,
against the spiritual things of the church.

CL 499

. . . natural people, even including carnal ones,
possess human rationality like others,
yet that they use it only
when engaged in their outward lives,
but abuse it when engaged in their inner ones.

It is in consequence of this
that one ought not to base his judgment of a person
on the wisdom of his lips alone,
but on the wisdom of his life too.
