We will always have to deal with someone we don’t like, at church, at work, maybe in our own family. Here’s some good advice from Lorenzo Scupoli, (1530 – 28 November 1610) who was the author of Il combattimento spirituale (The Spiritual Combat), one of the most important works of Catholic spirituality.
“If thy disturbance of mind proceeds from a person who is so disagreeable to thee, that every little action of his annoys or irritates thee, the remedy is to force thyself to love him, and to hold him dear; not only because he is a creature formed by the same sovereign hand as thou art, but also because he offers thee an opportunity (if thou wilt accept it) of becoming like unto thy Lord, who is kind and loving unto all men.”
“These things I command you, that you love one another.” John 25:17
