John Chrysostom

"Wisdom has built her house, and has set seven pillars." Since wisdom is the Son of God, once he became man he built his house, that is, the flesh from the Virgin. He [Solomon] calls the seven pillars "the spirit of God, the spirit of wisdom and understanding, the spirit of counsel and strength, the spirit of knowledge and piety, the spirit of the fear of God," as Isaiah says. [Solomon] also calls the church "house" and the apostles "pillars." The wise individual is the one who is safe and self-sufficient, lacking nothing. As the house of wisdom is the church, the pillars are those who appear to be pillars in the church.
