I had never even heard of this movement until this thread, but it seems like just another one of the many pragmatic programs that are around today.
I am definitely for mentoring within our Churches, but I am afraid that based on what I have read of this program, it is based more on the subjective, than the objective Word of God.

A side note.
About five years ago, I was a person that could not see anything wrong with movements like the Seeker Sensitive Movement. The arguments against that movement seemed at the time to be based on unwarranted reading into the movement itself. Sure I thought that there could be a danger if one wasn't careful. But it seemed to me that the critiques were painting all seeker sensitive Churches with the same brush. I believed at the time if one stayed true to correct soteriology, then there would be nothing wrong with being a seeker sensitive Church.

Since then however, I slowly began to see that the whole philosophy of the movement was flawed. It starts with the idea that getting the seeker through the doors of the Church in a manner they can relate to.
In other words it is geared around the seeker as the object of ministry, rather than on what a worship service is supposed to be geared to, on God Himself.
I have since learned that some Churches that are into being seeker sensitive, are like I was, not even conscious that they are doing this. If you asked them what a worship service was, they would probably correctly say a Church service is for the worship of God.
Unfortunately, in practice whether they know it or not, they gear their services around seekers, not God.

I bring the side note up because I suspect Emmaus is similar in a lot of ways to the seeker movement.
