Mark 3:17

And James the son of Zebedee, and John the brother of James; and he surnamed them Boanerges, which is, The sons of thunder:

Ver. 17. Boanerges] Syr. Benai regeschi, filii fragoris. Nazianzen saith they were so called, δια το μεγαλοφωνον, for the volume of their voice. Farellus was famous for his loud speaking, when the envious monks rang the bells to drown his voice as he was preaching at Metis, ille contra ad ravim usque vocem intendit, nec vinci se a strepitu ullo passus est. (Melch. Adam.) But there may be a great deal of force in a low language. Basil was said to thunder in his preaching, lighten in his life. Jerome was called Fulmen Ecclesiasticum, thunder of the chucrh, Athanasius Magnes et Adamas, A loadstone for his sweetness, and an adamant for his stoutness. The apostles had fiery tongues, but yet cloven. Barnabas and Boanerges "the son of consolation and of thunder," make a good mixture. The good Samaritan pours in wine to search the sores and oil to supple them. Discretion must hold zeal by the heel, as Jacob did his brother; these two must be as the two lions that supported Solomon's throne. He that hath them, may be a Moses for his meekness and a Phineas for his fervour. It was a good caution that Oecolampadius gave Farellus, Evangelizatum, non maledictum missus, et laudo zelum, modo non desideretur mansuetudo. Thou art sent, not to rail, but to reveal holy trust in meekness of wisdom.
