A Voice from the Past - Chrysostom

The cross is the impregnable wall, the invulnerable shield, the safeguard of the rich, the resource of the poor, the defense of those who are exposed to snares, the armor of those who are attacked, the means of suppressing passion, and of acquiring virtue, the wonderful and marvelous sign.

John Chrysostom, 347-407 AD, Against Marcionists and Manichaeans, 2 (translated by Rev. W. R. W. Stephens, Nicene and Post-Nicene Fathers, Philip Schaff, Henderson Publishers, 2012, First Series, Vol. 9, p. 204).

What are the implications of the cross? How do we make them real in our life?
