This challenging quite comes from James Payton Jr’s book Getting The Reformation Wrong:
Even so, the multitudes of church splits which have ensued in Protestant ranks – beginning already in the 16th century, increasing in frequency subsequently and achieving breakneck pace by the early twenty first century – have unquestionably managed to undermine the integrity of the gospel. The converse of what Jesus Christ prayed for (John 17) has come to pass: our lack of unity has rendered the gospel less credible in the eyes of the world. In this regard, we have sown the wind and have reaped the whirl wind. pg 257
