Alphonsus Liguori,
Sermons for all the Sundays in the year…
(1882)
“ The tongue is one of the members of the body, but when it utters bad words it infects the whole body, and "inflames the wheels of our nativity ;" it inflames and corrupts our entire life from our birth to old age. Hence we see that men who indulge in obscenity, cannot, even in old age, abstain from immodest language. ”
