John of Damascus — on Gal 1:1

“Why did he not start with what befits the Godhead of Christ, but with the very passion? He did so because they rebelled against him as those who would be punished if they deviated from the law; and so he mentions that thing through which every need of the law has been thrown out. I mean, of course, the cross and the resurrection, which provided the cause for the salvation of all.”
