Universal love

In Christian theology charity, Latin caritas, is by Thomas Aquinas understood as "the friendship of man for God", which "unites us to God". He holds it as "the most excellent of the virtues". Further, Aquinas holds that "the habit of charity extends not only to the love of God, but also to the love of our neighbor".

Some delineate charity to mean only benevolent giving, while others, such as Roman Catholics, have multiple interrelated meanings (i.e. charity is the theological virtue by which we love God above all things for his own sake, and our neighbor as ourselves for the love of God).

In Christian theology charity is the greatest of the three theological virtues. Thomas Aquinas does not simply equate charity with "love", which he holds as a passion, not a virtue; rather, translators use the word "friendship", as stated above.

The phrase Deus caritas est from 1 John 4:8—or Θεὸς ἀγάπη ἐστίν (Theos agapē estin) in the original Greek —is in line with the translation from Douay-Rheims:

In contrast with the translation from KJV:

Charity is held to be the ultimate perfection of the human spirit, because it is said to both glorify and reflect the nature of God. Confusion can arise from the multiple meanings of the English word "love". The love that is caritas is distinguished by its origin, being divinely infused into the soul, and by its residing in the will rather than emotions, regardless of what emotions it stirs up. According to Aquinas, charity is an absolute requirement for happiness, which he holds as man's last goal.

Charity has two parts: love of God and love of man, which includes both love of one's neighbor and one's self.

Paul describes it in the First Letter to the Corinthians, chapter 13 (KJV):
