The following is from the Barmen Declaration, a document written in 1934 in response to compromises made by professing evangelicals who gave in to the pressure of the Nazi party. Signers and writers of the Barmen Declaration included members of the Lutheran, Reformed, and United churches. Karl Barth was the key writer of the document, and Deitrich Bonhoeffer was a key signer.
Try the spirits whether they are of God! Prove also the words of the Confessional Synod [i.e. the group writing this document] of the German Evangelical Church to see whether they agree with Holy Scripture and with the Confessions of the Fathers.

The unimpeachable basis of the German Evangelical Church is the gospel of Jesus Christ as it is testified to in the Holy Scripture and brought to light again in the Confessions of the Reformation.

It has thereby forfeited the claim to be the legitimate administration of the German Evangelical Church.
