We had our zoom meeting as usual last Wednesday, looking at 1 Timothy 6:6-10 and focusing on those great and complimentary texts Godliness with contentment is great gain and For the love of money is a root of all kinds of evil. We also spent time in prayer and many prayed. Prayer is so important. I doubt that we fully realise that.
The similar phrase 'Worldly Christianity' is one used by Bonhoeffer. 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.
