“We need to understand that God will often test us by using a man such as XX. He will test to see which is more important to our spirits: a love of Jesus Christ, and of men and of lost souls, and of obeying the Holy Spirit, (despite doctrinal camps), or the cold, calculated love of theology.”

Right or wrong, we have to consider some truth here. But never forget that all false and all lies shall be confronted in the name of Jesus.

A man that is a heretic after the first and second admonition reject; Titus 3:10

It is on the other hand of must importance that we don’t put doctrine before the Gospel and the effort of cooperation with absolutely everybody who’s intention is to harvest people for eternal life.

But there is a line, even how thin. The line is in Heb 6.

1 Therefore leaving the principles of the doctrine of Christ, let us go on unto perfection; not laying again the foundation of repentance from dead works, and of faith toward God,
2 Of the doctrine of baptisms, and of laying on of hands, and of resurrection of the dead, and of eternal judgment. 3 And this will we do, if God permit.

If we can’t agree on this we can not go any further in cooperation. Because we are commanded to go on to perfection and if the foundation is not right that will be impossible.

As we can read it contains the doctrine of baptism and laying of hands. Let’s start there. And let’ see what will happened. Not much, because it will rule out cooperation with nearly every denomination if you want to stand on Word of God without compromising.

Therefore we have to come away and out of denominations and into no-denomination. Away with Lutheran, Baptist, Methodist, Salvation Army, Pentecostal and so on and so forth. (RCI and other sects are already gone)

Is it is possible? Yes; All things are possible with Jesus.
