I think we have to be careful about ascribing evil intent or motives to churches like you describe. Coaches that use the no huddle offense are just taking advantage of the enemy's weakness.
I think a huge motive behind the packaging you describe is to get people in church who would otherwise be sitting on their rumps at home. Some (many) of those folks really get saved.
We can argue about whether the packaging is the right way to go about it but it seems to work, and I don't think there is evil intent behind it.
I would much rather have unsaved friends and loved ones attend a church they like than not attend a church they don't like.
I want to be careful, too. I'm sick of armchair QB'ing the church (to keep with our football analogy for now), and I'm guilty. You can simply rage at the darkness or be a light to those who are in it. I'm praying for the prophetic gift to come alive in the church to lovingly and sternly warn the church.
I have a degree in communications. The writings of Neil Postman and the thoughts of Marshall McLuhan (who coined the famous phrase, "the medium is the message") and of men like Malcolm Muggeridge have been aimed in the last 50 years toward describing this thing we now see. (I recommend Postman's "Amusing Ourselves To Death" and "Technopoly".) I want to admit my bias here, and explain that I am not condemning anyone with "evil intent or motives". I do not contend that anyone is intentionally setting out to do what they see as evil. I do contend that what they are doing is a kind of evil.
When I say that there has been a conscious effort to move the church to this "look to the stage, this is where God is happening" way of being, I am speaking of it as a communicative technology. The church's way of expressing itself IS its own message, and it simply is not the gospel of Jesus. It competes with the gospel. It serves, practically, to oppose the gospel. It creates a different kind of "hearer", and by extension, a different kind of "doer" than that which Jesus is calling and empowering and sending forth. That is the "evil" I contend occurs, and while evil is not the overt motive for these actions, it is deliberate action and evil the covert effect.
You say, "a huge motive behind the packaging you describe is to get people in church." But, the "in church" part of that outweighs the motive. The packaging has become the church; and, the packaging has become the content of another gospel and the substance of what it means to be part of a church. The packaging is more than a mailer to pique interest; it is a full on way of being that is the model of Christian living, and it is centered on what happens in these buildings during an hour or two of singing, performing and public speaking.
That "some (many) of those folks really get saved" is the end justifying the means. Let's assume that this statement (many are saved) is true. Are the lives of those saved then modeled into Christ in these fellowships? If American churches are successfully modeling and leading people to Christ-like living, the fruit of it is sorely lacking. To the extent that many of those folks really get saved, this way of being the church is manifestly working against their further maturity in Christ, against their further glorifying God day to day. It is a hard case to make to them, though, since they tend to enjoy the way it is to their own detriment.
I simply do not see that "attend a church they like" is a lesser evil to "not attending a church they don't like" if the process of both is not bearing fruit to the glory of God in actual human lives that are being transformed into the image and likeness of Jesus. I respectfully think we may have very different understandings of what it means to say "it seems to work".
This is precisely why the problem is pernicious. It is not well understood when people with facially right motives take real action to move people from "rumps at home" to church are held to a scrutiny of the ways in which they communicate a message. People tend to think that the means of communication are value-neutral and that is simply not true. The means of communication -- the medium of communication, that is -- comes loaded with its own values that can taint or change the pure gospel and the full out-living of the pure gospel.
The early church was conscious of this. Judaism itself was word based, not image based. Words as media have vastly different values than images. From early on, "I AM" has not shown Himself in images, and has made the knowledge of Himself through images anathema. God presented Himself as a God of words to the prophets, and in the fullness of time came in the fullness of human flesh as the Living Word. John's writings go overboard in making this clear about Jesus as the Word.
The church today presents the gospel as image. The church package is the image of the gospel. The church package is therefore the substance of the gospel. This is subtle and largely unnoticed to "the church", but not to those who know God as Word and are shaped by Him as the Word Alive. The life of those who know God, who know the gospel, as "Word Alive" is vastly different from those who know the gospel as the packaged content of the contemporary American church (in Australia at least, too). The fruit of those who know God as Word Alive is different from those who know Him as the content packaged in an image at church services. The church that knows God as the Word who is alive empowers itself among its members with a deeper, abiding internalization of the Word and presents a Word based proposition to the lost. The church that knows God as an image, even an image that has "saved" them, empowers itself by coming to the scene of an event (a church service) and needing an external affirmation of the continuing truth (that the image of God as seen and experienced through the church service package still 'works' this week) and presents the quality of the image and the interaction with this image to the lost. These are not differing qualities; these are differing kinds of being. And, I submit to you that the latter is evil even if it doesn't "intend to be", per se.
Going back once more and more deeply to the football analogy, it is a different game. It uses footballs and helmets (or, crosses and bibles), it uses bleachers (or, pews or chairs), it blows whistles and calls plays (or, uses the lingo and jargon of the faith). It calls itself college football, and a lot of money is staked on people buying it as college football. But, it isn't football. It is a different game (a different gospel), and you can see the impact it has on what still is real football in the NFL (or, the church that knows God as the Word Alive) because almost nobody knows how to play real football when they arrive in the NFL (or, nobody knows how to model biblical Christ-likeness to each other or demonstrate it to the lost) and they either are slow to develop (or, they will hopefully come around to the truth one day) or the overall game (faith) is suffering through a change from what it was to what it will be --- which is something very different in kind (not biblical).
