“If you find yourself in front of – imagine! – in front of an atheist and he tells you he doesn’t believe in God, you can read him a whole library, where it says that God exists and even proving that God exists, and he will not have faith. But if in the presence of this atheist you bear coherent witness of Christian life, something will begin to work in his heart. It will be your witness that that he will bring this restlessness on which the Holy Spirit works. It’s a grace that we all, the whole Church must ask for: ‘Lord, [grant] that we might be coherent.’”
— Pope Francis, homily on February 27, 2014.
