The Bible for the Sick was first published early in the 20th century. Compiled by Antoine Ozanam, the saintly founder of the Society of St. Vincent de Paul, it is now available again from Roman Catholic Books. Msgr. Ignacio Barreiro of Human Life International calls it an “extremely valuable compendium of Bible passages for the seriously ill.”
Here is one passage I think is especially helpful:
Fear Not Death
O Death, how bitter is the remembrance of thee
To a man that hath peace in his possessions:
To a man that is at rest, and whose ways are prosperous in all things,
And that is yet able to take meat!
O death, thy sentence is welcome to the man that is in need,
And to him whose strength faileth,
Who is in a decrepit age, and that is in care about all things,
And to the distrustful that loseth patiene!
Fear not the sentence of death.
Remember what things have been before thee,
And what shall come after thee:
This sentence is from the Lord upon all flesh:
And what shall come upon three by the good pleasure of the most High?
Whether ten, or a hundred, or a thousand years.
(Eccli. XLI. 1-6)
