Can I give you an example of what I mean so that we are clear what I mean when I say watered down?
I attended an evangelical Friends (Quaker) church throughout my junior high and high school years. By being evangelical it had already drifted from its Quaker roots, but it still held to pacifism, anti-sacramentalism, and arminianism. Every worship service we spent 15-20 minutes in silent spiritual communion the way Friends do.
Today this church still maintains the Friends name, but it has become a generic Evangelical church. Gone is the pacifism, the anti-sacramentalism, and the arminianism, as well as the practice of spiritual communion. Instead of being opposed to water baptism, they now teach you have the choice of being baptized or not, as you wish. Totally non-committal, as if it doesn't matter. Instead of being opposed to breaking bread and sharing the cup, they now teaching that you can have communion or not as you wish. Totally noncommittal, as if it doesn't matter. They take no stand on war, whether pacifism or just war or anything else. It is entirely up to the individual believer, with no guidance from the church at all. As if it doesn't matter.
It's not that I agree with the old Quaker views. I definitely do not. Indeed, I became a Catholic because I believe quite differently. But at least before they stood for something. Now they have no depth at all. They are not guiding their parishioners through the issues, or the storms of life. It's just "receive Jesus." As if that were the only thing that matters.
So, because you are lukewarm--neither hot nor cold--I am about to spit you out of my mouth.
