The Minnesota Christian Chronicle, an Evangelical biweekly paper out of Golden Valley, Minnesota shows in its December 16 issue why it is often hard to work with the separated brethren. Two examples will suffice.
In a nearly five full pages of analysis of the year in review, focusing mostly on the presidential elections, Warren Smith and Jamie Dean In their "Mapping the World in Reds and Blues" manage to completely ignore developments in the Catholic Church in the US that help account for the victory of pro-lifers and Republicans at the polls. I'm not sure if this is simply ignorance on the part of the editors or a policy on the part of the paper to never include Catholics as Christians in their "Chronicle." Remarkable, but sad that neither would surprise me a whit.
The other example is a column by editor by editor Brian Flynn titled "Christians Should Dump Contemplative Prayer." Flynn claims he is a former New Age medium and sees now that "New Age" practices have invaded Christianity. While he is undoubtedly right that some contemplative practices from the East are unacceptable (and Flynn is right to note Thomas Keating and Thomas Merton as crossing unacceptable lines), he seems to believe that any contemplative practice is unacceptable. The key principle is that techniques, and that means any technique including reading the Bible, are not the source of Christian prayer. God is the source and technique can only help dispose one to hear God's voice. But Flynn's broad puritan brush can't even make a distinction like this one.
