Sons of Thunder

Nec Jacobus et Joannes mortui filii tonitrui, quibus in usum gloriae coelestis assumptis non praevalent terrena, sed subjacent. Esto ergo et tu Petrus, devotus, fidelis, pacificus; ut portas Ecclesiae aperias, et portas mortis evadas. Esto filius tonituri. Dicis: Quomodo possum esse filius tonitrui. Dicis: Quomodo possum esse filius tonitrui? Potes esse, si non in terra, sed in pectore Christi recumbas. Potes esse filius tonitrui si te terrena non moveant, sed ipse potius ea quae terrena sunt, mentis tuae virtute concutias. Tremat te terra, non capiat: vereatur caro potestatem animi tui, et concussa subdatur. Eris filius tonitrui, si fueris filius Ecclesiae. Dicat et tibi de patibulo crucis Christus: 'Ecce mater tua'  Dicat et Ecclesiae: Ecce filius tuus ; tunc enim incipis esse filius Ecclesiae cum in cruce victorem videris Christum. Nam qui crucem scandalum putet, Judaeus est, Ecclesiae filius non est: qui crucem stultitam putat, Greacus est. Ille autem est Ecclesiae filius, qui crucem triumphum putat, qui crucem Christi triumphantis agnoscit.   Sanctus Ambrosius Mediolanensis, Evangelii secundum Lucam, Liber VII

Neither James nor John, the sons of thunder, 1 died; they were taken up to the enjoyment of heavenly glory because earthly things did not prevail over them but they subdued them. Be then a Peter, devout, faithful, peaceful, that you may open the gates of the church and avoid the gates of death. Be a son of thunder. You may ask, 'How am I able to be a son of thunder?' You are able to be one if you recline on the breast of Christ, 2 not on the earth. You are able to be a son of thunder if earthly things do not move you, but rather you, with the virtue of your mind, crush down worldly things. Let the earth fear you, rather than seize you, let flesh fear the power of your soul and let it be subdued with a blow. You shall be a son of thunder if you become a son of the Church. Let Christ say from the yoke of the cross: 'Behold your mother.' 3 And let it be said to the Church 'Behold your son' 4 Then you shall begin to be a son of the Church when in the cross you see the victory of Christ. For he who thinks the cross scandalous is of the Jews; he is not  a son of the Church. He who thinks the cross is foolish, is of the Gentiles. He is a son of the Church who deems the cross a triumph, who knows the cross as the victory of Christ. Saint Ambrose, On The Gospel of Luke, Book 7 1 Mark 3.17 2 Jn 13.23-25 3 Jn 19.27 4 Jn 19.26
