Tertullian, on Ps 110:10

“The fear of the Lord is the beginning of wisdom. A good understanding to all that do it: his praise continueth for ever and ever.”

“It has also been a subject of discussion, how extremely frequent is the intercourse that heretics hold with magicians, with charlatans, with astrologers, with philosophers; and the reason is that they are people who devote themselves to curious questions. "Seek, and you shall find," is everywhere in their minds. Thus, from the very nature of their conduct may be estimated the quality of their faith. In their discipline we have an index of their doctrine. They say that God is not to be feared; therefore all things are in their view free and unchecked. Where, however, is God not feared, except where he is not, there truth also is not. Where there is no truth, then, naturally enough, there is also such a discipline as the heretics. But where God is, there exists "the fear of God, which is the beginning of wisdom." Where the fear of God is, there is seriousness, an honorable and yet thoughtful diligence, as well as an anxious carefulness and a well-considered admission [to the sacred ministry], a safely guarded communion, promotion after good service, a scrupulous submission [to authority], a devout attendance, a modest gait, a united church and God in all things.”
