As painful as it may be, the Church seems to prosper best when it is suffering persecution.
Not that I WANT to be persecuted, mind you!
I do, however, believe there is a certain type of cultural defeatism which is gaining ground in both broadly evangelical and confessionally Reformed circles.
The speaker may not hold that view. I don't know.
What I do know is that when a culture which once accepted Christian values, though often for secular reasons, makes a massive shift to the point that it openly embraces wickedness, things have not improved.
There are good secular reasons to support marriage, thrift, work ethics, sexual morality, and other cultural manifestations of Christian ethics.
A culture which throws those values away will rapidly move from tolerating Christians as a minority faith to openly despising and attacking Christians for being “intolerant” or otherwise rejecting the new anti-Christian secular ethics.
Such a culture also will not last very long. It will either wither into irrelevance or be replaced by some sort of secular or non-Christian faith which aggressively advocates its own version of cultural conservatism.
I freely grant that there are secular systems and non-Christian faiths which can work to one degree or another in building a culture on a different foundation. Islam, as bad as it is, did successfully build a culture. Similar things could be said for the role of Confucian ethics in Asia. Of course, those systems have horrible problems because they are built on the wrong foundation, but at least they are founded on something.
The moral relativism which is inherent in liberalism is not in that category. Put bluntly, liberalism doesn't work. It is an acid which destroys culture, not a system of beliefs which provide a foundation for culture.
I fear we are going to learn that the hard way.
