22. The cock at the summit of the church is a type of preachers. For the cock, ever watchful even in the depth of night, giveth notice how the hours pass, wakeneth the sleepers, predicteth the approach of day, but first exciteth himself to crow by striking his sides with his wings. There is a mystery conveyed in each of these particulars. The night is this world: the sleepers are the children of this world who are asleep in their sins. The cock is the preacher, who preacheth boldly, and exciteth the sleepers to cast away the works of darkness, exclaiming, 'Woe to them that sleep! Awake thou that sleepest! [Footnote 153] And these foretell the approach of day when they speak of the Day of Judgment, and the glory that shall be revealed: and like prudent {23} messengers, before they teach others, arouse themselves from the sleep of sin by mortifying their bodies. Whence the Apostle, 'I keep under my body.' [Footnote 154] And as the weathercock faceth the wind, they turn themselves boldly to meet the rebellious by threats and arguments: lest they should be guilty, 'when the wolf cometh, of leaving the sheep and fleeing.' [Footnote 155] The iron rod, whereon the cock sitteth, representeth the discourse of the preacher, that he speaketh not of man but of God: according to that saying, 'If any man speak, let him speak as the oracles of God.' [Footnote 156] But in that the iron rod is placed above the cross, on the summit of the church, it signifieth that Holy Scripture is now consummated and confirmed. Whence saith our Lord in His Passion, 'It is finished': and that title is written indelibly over Him. [Footnote 153: Eph. v, 14.] [Footnote 154: 1 Cor. ix, 27.] [Footnote 155: S. John x, 12.] [Footnote 156: I S. Peter iv, 11.] 23. The cone, that is the summit of the church, of great height, and of round shape, signifieth how perfectly and inviolably the Catholic faith must be held: which faith except a man do keep whole and undefiled, without doubt he shall perish everlastingly. 24. The glass windows in a church are Holy Scriptures, which expel the wind and the rain, that is all things hurtful, but transmit the light of the true Sun, that is, God, into the hearts of the faithful. These are wider [Footnote 157] within than without, because the mystical sense is the more ample, and precedeth the literal meaning. Also, by the windows the senses of the body are signified: which ought to be shut to the vanities of this world, and open to receive with all freedom spiritual gifts. [Footnote 157: This passage is particularly to be observed, for the reason given in the Introduction.] 25. By the lattice work [Footnote 158] of the windows, we understand the prophets or other obscure teachers of the Church Militant: in which windows there are often two shafts, signifying the two precepts of charity, or because the apostles were sent out to preach two and two. [Footnote 158: See Appendix I.] {24}
