'And it came to pass, that after three days they found him in the temple, sitting in the midst of the doctors, hearing them and asking them questions. [Lk 2.46] . . . The three days represent understanding one's own wickedness, compassion for one's brother's need, and consideration and admiration of the divine pity. . .

The second is in Ezekiel: This was the vision running to and fro in the midst of the living creatures, a bright fire and lightning going forth from the fire. [Ezek 1.13] The bright fire is the compassion of charity, which burns and enlightens, from which goes forth the lightning of wonderful works. This vision, which truly confers sight, must run to and fro in the midst of the living creatures, Christians. 'Running to and fro' is an appropriate term, since it runs in all sorts of ways. For true compassion, it is not enough to provide only for corporal needs, without providing for the soul too, and vice versa. If anyone is weak in body, it feels weak too; and if anyone is hurt in soul, it burns as well [cf. 2 Cor 11.29].'
