The apse signifies the faithful laity; the crypts, the hermits. The nave signifies Christ, through whom lies the way to the heavenly Jerusalem; the towers are the preachers and prelates, and the pinnacles represent the prelates’ minds which soar on high. Also a weather-cock on top of the church signifies the preachers, who rouse the sleeping from the night of sin, and turning ever to the wind, resist the rebellious. The iron rod upholding the cock is the preacher’s sermon; and because this rod is placed above the cross on the church, it indicates the word of God finished and confirmed, as Christ said in His passion, “It is finished.” The lofty dome on which the cross is set, signifies how perfect and inviolate should be the preaching and observance of the Catholic Faith. The glass windows of the church are the divine Scriptures, which repel the wind and rain, but admit the light of the true sun, to wit God, into the church, that is, into the hearts of the faithful. The windows also signify the five senses of the body.[89] The door of the church (again) is Christ--“I am the Door”; the doors are also the Apostles. The pillars are the bishops and doctors; their bases are the apostolic bishops; their capitals are the minds of the doctors and bishops. The pavement is the foundation of faith, and also signifies the “poor in spirit,” also the common crowd by whose labours the church is upheld. The rafters are the princes and preachers in the world, who defend the church by deed and word. The seats in a church are the contemplative in whom God rests without offence. The panels in the ceiling are also preachers who adorn and strengthen. The chancel, the head of the church, by being lower than the rest, indicates how great should be the humility of the clergy. The screens by which the altar is separated from the choir signify the separation of heavenly beings from things of earth. The choir stalls indicate the body’s need of recreation. The pulpit is the life of the perfect. The horologe signifies the diligence with which the priests should say the canonical hours. The tiles of the roof are the knights who protect the church from pagans. The spiral stairways concealed within the walls are the secret knowledge had only by those who ascend to the heavenly places. The sacristy, where the holy utensils are kept and the priest puts on his vestments, signifies the womb of the most holy Virgin, in which Christ put on His sacred garb of flesh. From thence the priest emerges before the public, as Christ went forth from the Virgin’s womb into the world. The lamp signifies Christ, who is the light of the world; or the lamps signify the Apostles and other doctors, whose doctrine lights the church. Moses also made seven lights, which are the seven gifts of the Holy Spirit.
