The capital should not be selected for heathen or pagan, for these words do not sufficiently specify any particular belief or association.
Indirect references to the Bible, as in Scriptures, Gospels, Psalms, etc., should begin with a capital. The same rule should be applied to important divisions of the Book of Common Prayer, as the Collects, the Litany, etc.
The words hell, purgatory, and paradise are now seldom capitalized, but Hades, Walhalla, and other poetical names of a future abode should have the capital always.
ABSTRACT QUALITIES PERSONIFIED
Abstract qualities, when personified in exclamatory addresses, always should be capitalized, as:
O Liberty! what crimes are committed in thy name!
O Fame! thy smile forebodes a frown.
Some writers give a capital to an abstract quality that is not clearly personified and is not at all exclamatory, as War, Slavery, Temperance. This is not a wise use of the capital, but it must be copied when the intent of a writer is plain.
A youth to Fortune and to Fame unknown.
And Scandal at her shot no venom'd shaft.
Then Crime ran riot.
Let Fate do her worst!
Now comes Peace to bless the land.
