Commemoration of John Bosco, Priest, Founder of the Salesian Teaching Order, 1888 "Secret" sins, such as are not known to be sins (it may be) to ourselves, make way for those that are "presumptuous". Thus pride may seem to be nothing but a frame of mind belonging unto our wealth and dignity, or our ... abilities; sensuality may seem to be but a lawful participation of the good things of this life; passion and peevishness, but a due sense of the want of respect that we must suppose owing unto us; covetousness, a necessary care of ourselves and of our families. If the seeds of sin are covered with such pretences, they will in time spring up and bear bitter fruit in the minds and the lives of men; and the beginning of all apostasy, both in religion and in morality, lies in just such pretences. Men plead that they can do so-and-so lawfully, until they can do things openly unlawful.
