We had a good number (14) out at our midweek meeting yesterday. Still some missing. We returned to Philippians, looking at the first five verses of Philippians 2, where Paul pleads for a fivefold unity (like-mindedness, mutual love, unity of spirit and purpose, humility not selfish ambition or vain conceit and looking not only to your own interests but also those of others) on the basis of the four or five matters of agreement already present (encouragement from being united with Christ ... comfort from his love ... fellowship with the Spirit ... tenderness and compassion). What a passage! Good time of prayer too - so much to pray about.
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.
