Tertullian

You must know that in the eye of perfect, that is, Christian, modesty, (carnal) desire of one's self (on the part of others) is not only not to be desired, but even execrated, by you: first, because the study of making personal grace (which we know to be naturally the inviter of lust) a mean of pleasing does not spring from a sound conscience: why therefore excite toward yourself that evil (passion)? why invite (that) to which you profess yourself a stranger? secondly, because we ought not to open a way to temptations, which, by their instancy, sometimes achieve (a wickedness) which God expels from them who are His; (or, ) at all events, put the spirit into a thorough tumult by (presenting) a stumbling-block (to it). We ought indeed to walk so holily, and with so entire substantiality of faith, as to be confident and secure in regard of our own conscience, desiring that that (gift) may abide in us to the end, yet not presuming (that it will).
