These are just my personal thoughts...
I read/consume ideas from a variety of places and perspectives. From Atheism to Islam, to Judaism. Certainly we as believers need to be discerning of truth (even in "Christian" media).
But the Phillips, Craig and Dean (and others) issue is a bit different. While there might not be anything objectionable in the content of the songs mentioned (because they were written by others and PCD are essentially doing covers of them), their personal theology is dangerously wrong.
Not only that, but they reject the Trinity, believe one must be baptized to be saved, speak in tongues as evidence of salvation, do other works to ensure salvation... and they still operate under the banner of "Christianity".
Furthermore, when these three pastors (yes they are pastors... so they have greater accountability here) are asked about their divergent theology... they are intentionally deceptive.
Here was their comments on the Trinity:
Affirming the "existence of the Father, the Son and the Holy Spirit – the Three in One."
"[w]e believe in one God who is eternal in His existence, Triune in His manifestation, being both Father, Son, and Holy Ghost and that He is Sovereign and Absolute in His authority."
To the average Joe (or Jill)... this sounds like standard Christian belief. But it's not. They believe in modalism (only one person who has taken on different roles in history) which is not historical Christianity.
And they know that.
Instead of coming out and honestly saying... "hey, we have different views. We don't believe in the Trinity. We don't believe in salvation by faith in Jesus through grace. And we think all of our listeners who don't speak in tongues are going to hell" .... they hide behind cleverly crafted statements that sound like they're saying one thing... but really saying another.
I ran into the same issue with PCD not too long ago... my personal solution was to find the songs (written by orthodox Christians) and download them from others.
For me... the issue here isn't about listening to or enjoying people with different viewpoints. I do that all the time. No. the issue is supporting and promoting people who pretend to be historical, orthodox Christians... but really aren't.... and then try to deceive people about what they really believe.
I'd rather buy a book from Richard Dawkins.
At least I know where he stands.
Again. Just my thoughts.
