The following is excerpted from Getting the Reformation Wrong: Correcting Some Misunderstandings by James R. Payton Jr. (IVP, 2010), pg. 124-125.

Today many mistake the Reformation emphasis on “sola fide” (“faith alone”) with an easy-believism where faith is all that matters and works are downplayed to the extreme that some view them as completely optional in the life of the Christian. James Payton in his book, explains that to the Reformers, faith was never so “alone”. Rather, they expected faith to always be accompanied by good works.

I found the following quotes from Philip Melancthon and Ulrich Zwingli quite helpful on this point.

Philip Melancthon [from his 1521 Loci communes theologici in Melancthon and Bucer ed. Wilhelm Pauck, Library of Christian Classics (Philadelphia: Westminster Press, 1969), pg. 92, 109 and 112] —

Faith is nothing else than trust in the divine mercy promised in Christ…. This trust in the goodwill or mercy of God first calms our hearts and then inflames us to give thanks to God for his mercy so that we keep the law gladly and willingly.

Faith cannot but pour forth from all creatures in most eager service to God as a dutiful son serves a godly father.

For although faith alone justifies, love is also demanded…. A living faith is that efficacious, burning trust in the mercy of God which never fails to bring forth good fruits.

Ulrich Zwingli [from his 1531 An Exposition of the Faith, in Zwingli and Bullinger, ed. and trans. G.W. Bromiley, Library of Christian Classics (Philadelphia: Westminster Press, 1953), pg. 272] —

But we must add at once that the pious will not cease from good works simply because it is impossible to gain any merit by them. Rather, the greater our faith, the more and greater our works…. For since faith is inspired by the Holy Spirit, how can it be slothful or inactive when the Spirit himself is unceasing in his activity and operation? Where there is true faith, works necessarily result, just as fire necessarily brings with it heat.
