Goat Rodeo Cowboy makes a good point. I'm a Lutheran Christian, and I'd be blessed to hear a Lutheran pastor preaching and doing a Lutheran Mass on the radio. My guess is, my Baptist brothers in Christ would be the one's calling the station telling the PD for 45 minutes that he's going to hell, because he's airing a mass, even a Lutheran one, first as Lutheran doctrine is different from Roman Catholicism (remember the 95 thesis Martin Luther posted on the church doors at Wittberg) and as some Lutheran doctrine is different from that of a Southern Baptist. The Penticostal brothers in Christ would be calling the station to complain about both the Lutheran and the Baptist broadcasts as neither has quite the same doctrinal beliefs as their church. It's unfortunate that we can't simply focus on the Jesus we all have in common. We all have different approaches to our worship of the Messiah, but the bedrock beliefs of salvation through the blood of Christ, virgin birth, etc, etc, are the same, which we rarely seem to celebrate. God, in his generosity, didn't create us with a cookie cutter making us all vanilla, but gave us many varied expressions that we have the opportunity to use to express our love, faith, and worship of his risen Son, Jesus, which we'll again be celebrating in two weeks as the season of Lent will then come to an end with Easter or Resurrection Sunday. Yes, my brother and sisters in Christ, who worship in non Liturgical type churches won't agree with my use of the word Lent, but again that is a time in the Luturgical church calendar where we followers of Christ take a look inward at our walk with Jesus and use that time to re-focus our lives on the soon to be risen savior.
To re-focus on Goat Rodeo's point, the PD at a Christian station has a difficult job, especially if he runs a commerical Christian station that accepts ads, but even the non-comms too, as the there will always be listeners who want to hear only the preachers that they agree with. That's why I don't listen to anything Harold Camping says, I don't agree with much of his doctrine, but love the music his network of stations air. But I don't call the Family Network arguing with the network PD or even the PD at WKDN asking them to pre-empt Campings rantings, I simply tune out when he's on, but as Goat Rodeo pointed out, many a PD at a Christian station has had his/her ear bent by irrate listeners who didn't like the music as being too comtemporary or that the preachers airing are preaching false doctrine. As Christian listeners, we do get to vote with our wallets, so support the radio preachers that you believe God has led you to support and ignore the others by simply tuning out. Even though I don't agree with much of what Harold Camping says, I believe the Lord can use his radio network to bring possibly millions to Christ (which is one of the few commands Jesus gives us to do), and as it's God's job to judge the quality of each of our efforts to bring people to him, not mine, I'll leave it in God's hands and simply enjoy the music and tune out Camping's preaching on Family Radio.
