The Reformation churches have some wonderful slogans that are chock full of important truths. Sometimes, however, these slogans can be misconstrued, misreported, and misunderstood. With the possible exception of sola Scriptura (by Scripture alone), none of these slogans has been mangled more often toward greater mischief than ecclesia reformata, semper reformanda (the church reformed, always reforming). According to historian Michael Bush, much of what we think we know about this slogan is probably wrong. The phrase is not from the sixteenth century. I have searched hundreds of documents in a variety of languages from the sixteenth and seventeenth centuries, and the phrase ecclesia reformata, semper reformanda does not occur in them. Neither does the phrase semper reformanda (always reforming). Certainly, the Reformed writers spoke of a "Reformed church" and of the necessity of reformation. But men such as Calvin, who published a treatise on the need for reformation in 1543, did not use the phrase. The Dutch Reformed minister Jodocus van Lodenstein (1620-77) first used something like it in 1674 when he juxtaposed "reformed" with "reforming," but he did not say, "always."
