Try to acquire the virtues you believe lacking in your brothers. Then you will no longer see their defects, for you will no longer have them yourself.
Saint AugustineO eternal truth and true love and beloved eternity! You are my God; to you I sigh by day and by night. And when I first knew you, you raised me up so that I could see that there was something to see and that I still lacked the ability to see it. And you beat back the weakness of my sight, blazing upon me with your rays, and I trembled in love and in dread.
Saint Augustine
