Neither can the work “On the Freedom of a Christian Man” be absolved from a certain dangerous radicalism. A false spirit of liberty in the domain of faith breathes through it. The faith which is here extolled is not faith in the olden and true meaning of the word, namely the submission of reason to what God has revealed and proposes for belief through the authority He Himself instituted, but faith in the Lutheran sense, i.e. personal trust in Christ and in the salvation He offers. Faith in the whole supernatural body of Christian truth comes here so little into account that it is reduced to the mere assurance of salvation. All that we are told is that the Christian is “free and has power over all” by a simple appropriation of the merits of Christ; he is purified by the mere acceptance of the merciful love revealed in Christ; “this faith suffices him,” and through it he enjoys all the riches of God. And this so-called faith is mainly a matter of feeling; a man must learn to “taste the true spirit of interior trials,” just as the author himself, so he says, “in his great temptations had been permitted to taste a few drops of faith.”[89] Faith is thus not only robbed of its true meaning and made into a mere personal assurance, but the assurance appears as something really not so easy of attainment, since it is only to be arrived at by treading the difficult path of spiritual suffering. Luther thereby strikes a blow at one of the most vital points of positive religion, viz. the idea of faith. The author, in this same work,[90] again reminds us that by faith all are priests, and therefore have the right “to instruct Christians concerning the faith and the freedom of believers”; for the preservation of order, however, all cannot teach, and therefore some are chosen from amongst the rest for this purpose. It is plain how, by this means, a door was opened to the introduction of diversity of doctrine and the ruin of the treasure of revelation. The religious tone which Luther assumed in the work “On the Freedom of a Christian Man,” and his earnestness and feeling, made his readers more ready to overlook the perils for real religion which it involved. This consideration brings us to the other characteristic, viz. the pietism which, as stated above, is so strangely combined in the three works with intense radicalism.
