Take as your one wisdom the science of the cross (cf. 1 Cor. 2:2). Look to the cross and you will find the solution to all the problems that assail you. If the cross is your criterion for making choices and decisions, you will be at peace. (Cardinal Van Thuan, Five Loaves and Two Fish)
To live by the “criterion” of the cross means to make the choice to love in all situations; heedless of the shame and heedless of any hoped for outcomes. To apply this criterion to all situations is a very demanding discipline but it is a path to true peace and to true hope.
