On Wednesday evening we had a helpful question session and then after the evening meal a second address from Alistair Begg, this time on Titus 2. Again it was very warm and beautifully illustrated with quotations and pictures. He began with a quotation from Dr Lloyd-Jones “The glory of the gospel is that when the church is different from the world, she invariably attracts it. It is then that the world is made to listen to her message, though it may hate it at first." He then observed how amazing it is that people today can square feminism, environmentalism and even yoga with Scripture. He then proceeded by isolating the verses addressed directly to Titus (2, 7, 15) and dealing with those first and then the various categories in the chapter before briefly tackling some of the other verses. He quoted Leo the Great on the deposit. It is "a thing not of wit, but of learning; not of private assumption, but of public tradition; a thing brought to thee, not brought forth of thee."
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.
