Joseph Barber Lightfoot, Dictionary of Christian Biography and Literature (1911)
“ The gentleness and serenity of Clement, whose whole spirit is absorbed in contemplating the harmonies of nature and of grace; the fiery zeal of Ignatius, in whom the one overmastering desire of martyrdom has crushed all human passion; the unbroken constancy of Polycarp, whose protracted life is spent in maintaining the faith once delivered to the saints,—these are lessons which can never become antiquated or lose their value. ”
