  • The Chief Sources of Sin: Seven Discourses on Pride, Covetousness, Lust, Anger, Gluttony, Envy, Sloth, by Michael V. McDonough [b. 1863] (New York, Baltimore: John Murphy Company, 1910). With Imprimatur. May be read online, and available in pdf, epub, mobi,. And other formats at Internet Archive and Open Library.
    • [N.B., This work appears to be in the public domain under US law. As to other jurisdictions, an online search yielded a date of death of 02 November 1933 for a certain Rev. Michael V, McDonough, chaplain of St. Mary’s Home, New Bedford (vide Anchor, October 29, 2010, p.19). If this is the author, then the work would also have entered the public domain in jurisdictions where the copyright period is reckoned based on the author’s lifetime + 70 years. Advice on this matter would be appreciated.]

“If, when I say to the wicked, Thou shalt surely die: thou declare it not to him, nor speak to him, that he may be converted from his wicked way, and live: the same wicked man shall die in his iniquity, but I will require his blood at thy hand. But if thou give warning to the wicked, and he be not converted from his wickedness, and from his evil way: he indeed shall die in his iniquity, but thou hast delivered thy soul.” (Ezechiel iii, 18-19)

“Jesus found him in the temple, and said to him, Behold, thou hast recovered thy strength; do not sin any more, for fear that worse should befall thee” (St. John v, 13)

If any man see his brother sin a sin which is not unto death, he shall ask, and he shall give him life for them that sin not unto death. There is a sin unto death… and there is a sin not unto death.” (II John v, 16-17 KJV)
