Good points about the old hymn writers and stuff. But their all dead now. I have no problem with any of the hymns that I've been exposed to. But Jesus Culture/ Bethel Music are present day, self proclaimed, global movements that are geared toward the youth in order to raise up a new generation of revivalists to take over the world. And this will, according to their beliefs, usher in the Lords return. This is Dominion theology. It is extremely flawed and dangerous. Check it out.
I don't know that much about Bethel's eschatology. I get the impression from some of the 'prophetic movement' types that they don't have a really specific theology. Some of those churches, sadly, do seem a bit light on Bible study, just based on the times I've visited them. I assume some of the people get their eschatological beliefs from their previous religious background. It could be dispensationalist, but with some 'positive' ideas about eschatology that seem a bit 'post mil' or 'dominionist.' They could have dispensational views, but with a twist that sees some positive things happening before the end.
I've read that a number of early Pentecostals came from a post-mil background. It was a mixed bag. Eventually, a more-or-less dispensational view took over the movement.
Plenty of preachers that most modern evangelical Protestants were post-mil in their outlook. I've read that Jonathan Edwards and many of the Methodists were.
I suspect some of these groups that people make these 'dominionist' comments about are full of people with basically dispensational views but with a bit of post-mil philosophy mixed in about great end-times revivals where some positive things would happen. But I also suspect a lot of these churches don't teach in depth on eschatology.
Lack of teaching of certain doctrine in certain churches does concern me, btw. But it doesn't make those who attend heretics.
I can't say Bethel doesn't have in depth Bible teaching. I don't know enough about them to say that.
Honestly, there's too much heresy to put in this post but in a nut shell, they place more emphasis on signs and wonders, subjective experiences, prophecy, and visions and dreams than they do on scripture.
The Bible places emphasis on these things. In the New Testament, Paul spent more space in his epistles emphasizing the importance of prophesying than he did on emphasizing the importance of expository Bible teaching. Both he and Peter had visions. Both went into a trance on at least one occasion. Paul and his team made a big ministry decision based on a vision.
What is 'too much emphasis'? There are some Bible teachers focus more than half of their teaching on end-times issues. A friend of mine went to a church where the preacher had a special session before or after the sermon to talk about newspaper headlines in the middle east to tie them in to some kind of pre-trib framework. That seemed like 'too much emphasis' to me. But it wouldn't bother me if it weren't for the pre-trib thing.
Is it heretical if a certain individual who has a ministry to the sick focuses an awful lot on healing, and another individual who is very much into economics and finance often teaches on being faithful with money, and someone else focuses a lot on counseling married couples and teaches on marriage? Signs and wonders are a valid, and Biblical, topic. So the 'emphasis' thing doesn't seem like heresy to me. If you want to accuse them of heresy, but specific. Don't just accuse them of riding a different hobby horse than your own.
Also the Bible also doesnt teach about pedophilia, but we know it's evil.
The Bible certainly has a lot to say that relates to the topic of pedophila, for example on the topics of fornication, rape, loving your neighbor as yourself, etc., even if it doesn't use the modern word 'pedophilia.'
I would strongly encourage you, if you havent already, to look up ihops and bethel church heresies. Theres a ton of research out there. As long as we test everything to scripture we'll be okay.
'Research' on websites like this often consist of pages of accusations based on unbiblical presuppositions about gifts of the Spirit ceasing or arguments similar to your 'too much emphasis' argument.
