In order to make the following quote more understandable:
Erasmus (1466-1536) was a great Renaissance scholar and one of Luther's chief opponents. Packer writes of Erasmus, "Christianity, to Erasmus, was essentially morality, with a minimum of doctrinal statement loosely appended. . . Erasmus cannot be acquitted of the charge of doctrinal indifferentism. . . however sure one might be that the Church was at some point wrong, one was never justified in disrupting Christendom about it (as Luther was doing); peace in the Church was of more value than any other doctrine." And on to the quote:
Has not Protestantism to-day become more Erasmian than Lutheran? Do we not too often try to minimize and gloss over doctrinal differences for the sake of inter-party peace? Are we innocent of the doctrinal indifferentism with which Luther charged Erasmus? Do we still believe that doctrine matters? Or do we now, with Erasmus, rate a deceptive appearance of unity as of more importance than truth? Have we not grown used to an Erasmian brand of teaching from our pulpits - a message that rests on the same shallow synergistic conceptions which Luther refuted, picturing God and man approaching each other almost on equal terms, each having his own contribution to make to man's salvation and each depending on the dutiful co-operation of the other for the attainment of that end? - as if God exists for man's convenience, rather than man for God's glory? Is it not true, conversely, that it is rare to-day to hear proclaimed the diagnosis of our predicament which Luther - and Scripture - put forward: that man is hopeless and helpless in sin, fast bound in Satan's slavery, at enmity with God, blind and dead to the things of the Spirit? And hence, how rarely do we hear faith spoken of as Scripture depicts it - as it is expressed in the cry of self-committal with which the contrite heart, humbled to see its need and made conscious of its own utter helplessness even to trust, casts itself in the God-given confidence of self-despair upon the mercy of Christ Jesus - 'Lord, I believe; help Thou my unbelief!'
