it is not enough to believe that he is God but that, impelled by charity, it is necessary to follow him on the same path, that of the Cross (cf. Mk 8:31–33). Jesus did not come to teach us philosophy but to show us a way, indeed the way that leads to life. This way is love which is an expression of true faith. If someone loves his neighbour with a pure and generous heart it means that he truly knows God. If instead someone says he has faith but does not love his brethren, he is not a true believer.
