For whoever falls into a pit by accident is considered unreasonable and they say he hit it wrong; but whoever deliberately falls into a pit is called crazy.

What you mentioned to me about religious practices, to this you have received an answer.

And the monkey has human limbs and in many things imitates man; is it for this reason that it is man?

So also heresy, all the mysteries of the Church it has and imitates, but the Church it is not.

Knowing that these were not overt pagans, but concealed under the name of Christianity, the Lord did not say: look, but beware; for to look is to set one’s eyes directly on a subject; to beware is to consider something comprehensively.

Where a thing is certain and undoubted, there one looks; and where uncertain and doubtful, there one considers.

Knowing therefore Christ the Lord that in them is something different on the surface and something different within hidden, He said:

“Beware,” that is, not so much with the eyes of the flesh as with the eyes of the spirit. For if you look at them with the eyes of the flesh, you will not recognise them; for they claim to be Christians and keep up appearances as Christians.
