On Works and Faith – Protestant teachers continue to propagate the fundamental error that all that matters is faith, and that out of faith works must necessarily proceed. This is simply not true: but it has so seductive a sound it has certainly confused other intelligences than Luther’s (namely those of Socrates and Plato): even though the evidence of every experience of every day speaks against it. The most confident knowledge or faith cannot provide the strength or ability needed for a deed, it cannot replace the employment of that subtle, many-faceted mechanism which must first be set in motion if anything at all of an idea is to translate itself into action. Works, first and foremost! That is to say, doing, doing, doing! The ‘faith’ that goes with it will soon put in an appearance – you can be sure of that.
