By Garrett Johnson, Catholic Exchange - As I sit before the Tabernacle this morning in prayer, I repeat the Jesus Prayer slowly to myself: Lord Jesus Christ, Son of God, have mercy on me, a sinner. As I do, questions I often ask myself circulate in the background of my mind: What is mercy? What does it mean to ask Jesus to be merciful to me in my times of difficulty and struggle? What does it mean for me as a Catholic to be merciful to my fellows who struggle with addiction, same-sex attraction, and sexual identity confusion?
