In his homily at Santa Marta the pope invited Christians to imitate Jesus with actions, even if the logic of the Gospel is contrary to the logic of the world.
POPE FRANCIS
“Bearing witness is breaking a habit, a way of being. Breaking it for the better, changing it. For this reason, the Church advances through witness. What is attractive to people is the witness. Not the words, which help, yes; but witness is what is attractive, and what makes the Church grow.”
In his last remarks, the pope warned of the danger of falling into an attitude opposed to bearing witness to Christ. In other words, an attitude of criticism and murmuring.
