Now it is evident that no one can terrify or subdue us who have believed in Jesus over all the world. For it is plain that, though beheaded, and crucified, and thrown to wild beasts, and chains, and fire, and all other kinds of torture, we do not give up our confession; but the more such things happen, the more do others and in larger numbers become faithful, and worshippers of God through the name of Jesus. For Just as if one should cut away the fruit-bearing parts of a vine, it grows up again, and yields other branches flourishing and fruitful; even so the same thing happens with us. For the vine planted by God and Christ the Savior is His people.
Justin Martyr. Second Century
