Catena Aurea · Lukasevangelium 12
I am come to send fire on the earth; and what will I, if it be already kindled? But I have a baptism to be baptized with; and how am I straitened till it be accomplished! Suppose ye that I am come to give peace on earth? I tell you, Nay; but rather division: For from henceforth there shall be five in one house divided, three against two, and two against three. The father shall be divided against the son, and the son against the father; the mother against the daughter, and the daughter against the mother; the mother in law against her daughter in law, and the daughter in law against her mother in law.
To stewards, that is, to Priests, the preceding words seem to have been addressed, that they may thereby know that hereafter a heavier punishment awaits them, if, intent upon the world’s pleasures, they have neglected the charge of their Lord’s household, and the people entrusted to their care. But as itprofiteth little to be recalled from error by the fear of punishment, and far greater is the privilege of charity and love, our Lord therefore kindles in men the desire of acquiring the divine nature, saying, I came to send fire on earth, not indeed that He is the Consumer of good men, but the Author of good will, who purifies the golden vessels of the Lord’s house, but burns up the straw and stubble.
