A Voice from the Past - Polycarp

Faith is the mother of us all; with Hope following in her train, and Love of God and Christ and neighbor leading the way. Let a man's mind be wholly bent on these, and he has fulfilled all the demands of holiness; for to possess Love is to be beyond the reach of sin.

Polycarp, 69-155 AD, Letter to the Philippians, 3 (Early Christian Writings, translated by Maxwell Staniforth, 1968, Penguin Books, p.145

Is this true? What implications does it have for us today?
