Those who do practise often function at a fairly minimal level, and are unfamiliar with the great Catholic writers — or even with the lesser ones — and have no sense of zeal or excitement about
imparting knowledge of the Faith, much less devotion to it.
Philipp Jacob Spener (1635 - 1705), the apostle
of Pietism, held that the aim
of preaching should be to «awaken
faith and [to] urge the fruits
of faith,» and hence that the aim
of ministerial training should be «not only to
impart knowledge but to have truth penetrate the soul.»
