When the Homily is about Immunology

Love

For love does not seek its own, it labors, sweats, watches to build up
the brother: nothing is inconvenient to love, and by the help of God it
turns the impossible into the possible .... Love believes and hopes ....
It is ashamed of nothing. Without it, what is the use of prayer? What
use are hymns and singing? What is the use of building and adorning
churches? What is mortification of the flesh if the neighbor is not
loved? Indeed, all are of no consequence .... As an animal cannot exist
without bodily warmth, So no good deed can be alive without true love;
it is only the pretence of a good deed.

-St. Tikhon of Zadonsk
