Luke 12:3

Or He says this, because all the things which the Apostles of old spoke and suffered amid the darkness of oppression and the gloom of the prison, arc now that the Church is made known through the world and their acts are read, publicly proclaimed. The words, shall be proclaimed on the housetops, are spoken according to the manner of the country of Palestine, where they are accustomed to live on the housetops. For their roofs were not after our way raised to a point, but flat shaped, and level at the top. Therefore He says, proclaimed on the housetops; that is, spoken openly in the hearing of all men.

The Gnostic, then, is impressed with the closest likeness, that is, with the mind of the Master; which He being possessed of, commanded and recommended to His disciples and to the prudent. Comprehending this, as He who taught wished, and receiving it in its grand sense, he teaches worthily "on the housetops" those capable of being built to a lofty height; and begins the doing of what is spoken, in accordance with the example of life. For He enjoined what is possible. And, in truth, the kingly man and Christian ought to be ruler and leader. For we are commanded to be lords over not only the wild beasts without us, but also over the wild passions within ourselves.

For what you have spoken in darkness will be heard in the light, and what you have whispered in the ear in chambers will be proclaimed on the rooftops, not only in the future, when all hidden things of the heart will be brought to light, but also in the present time it can be suitably interpreted. For the things which the apostles once spoke or suffered in the darkness of oppressions and shadows of prisons are now proclaimed publicly throughout the world by the Church, now made glorious by their acts being read. Indeed, what he says 'will be proclaimed on the rooftops' refers to the custom of the province of Palestine, where they are accustomed to sit on rooftops. For they do not make their roofs elevated to peaks in our manner, but they make them flat in a level form. Hence, the law commanded that he who built a new house should build a parapet around the roof, so that bloodshed may not occur there if someone were to fall and be precipitated down. And in the construction of the temple, we read: He also covered the house with cedar boards, and built a story over the entire house five cubits in height. Therefore, it will be proclaimed on the rooftops, and it will be said openly for all to hear.
