Dwight Lyman Moody (1837 – 1899), also known as D.L. Moody, was an American evangelist and publisher, who founded the Moody Church, Northfield School and Mount Hermon School in Massachusetts (now Northfield Mount Hermon School), the Moody Bible Institute in Chicago and Moody Publishers. Ira Sankey was solo singer/music director for their evangelistic campaigns in both the United States and Great Britain. He came to Britian in 1867, 1872, 1873, 1874, 1881/2 and 1891/2. An evangelical ,he was controversial in some quarters but received the support of Spurgeon and other sound preachers.
Bonhoeffer uses a similar phrase 'worldly Christianity'. It's J Gresham Machen that I want to line up most closely with. See his Christianity and culture here. Having done commentaries on Proverbs (Heavenly Wisdom) and Song of Songs (Heavenly Love), a matching title for Ecclesiastes would be Heavenly Worldliness. For my stance on worldliness, see 3 posts here.
