Well, so much for pulling out your hymnal and singing "Onward Christian Soldiers." Oh wait, that one's been bounced as too militaristic in today's mainlines anyway. And, God forbid, that a hymn would be sung in today's non-mainline protestant churches.....
Now now, in my non-mainline protestant church of about 200-300 people per service (2), we sing a blend of newer music with the older music. Works out fine.
But, back to the issue. The way things are going these days, my dad (a pastor) may end up getting a visit from the FBI for the same reason. And, he'd probably handle it in the same way that this pastor did. At least it ain't Canada. Yet.
The FBI dropped it like a hot rock once they figured out that the anonymous informant (read: cowardly person trying to overthrow the pastor) was lying to them. Good for them. Those agents aren't the problem, it's the management that's the problem.
