From the wikipedia article discussing the meaning of the motto "summum bonum":
"Summum bonum is a Latin expression meaning "the highest good", which was introduced by Cicero, to correspond to the Idea of the Good in ancient Greek philosophy. The summum bonum is generally thought of as being an end in itself, and at the same time containing all other goods. The term was used in medieval philosophy and in Kantianism, to describe the ultimate importance, the singular and overriding end which human beings ought to pursue. In the Thomist synthesis of Aristotelianism and Christianity, the highest good is usually defined as the life of the righteous and/or the life led in communion with God and according to God's precepts."

This 2016 election cycle has been aggravating for me, and it was somewhat comforting to recall the words from my old high school song:
Hail Trinity, oh TrinityHowever, even though I explained the etymology of my old T-Hi avatar, I still received a number of neo Nazi followers, so I changed my avatar yet again to a seemingly non controversial stuffed bunny rabbit photo.
We pledge our loyalty forever

Always to guide us
