That is a simplification, of course, and some might wonder if it goes any deeper. I consider that KIND ONE is a deep and abiding folly and that the distinction between it and KIND TWO is the same as between the Old Covenant and the New. While there are many ways for the saints to attempt to put new wine into old skins, let us look at five broad areas which are somewhat obvious. KIND ONE is a Christianity of the external, hoping to seep in to the soul, and KIND TWO is that of the internal, unavoidably infecting its world.
Allowing the good to go first, five categories of the internal Christian life are:
LIFE, LIGHT, LOVE, JOY, and FELLOWSHIP.
Those matching in the external life are:
CULTURE, CREED, LAW, ENTERTAINMENT, and FACTION.
Do you realize, as you look at those lists, that everything you have ever complained about in the Church, at least in other churches, is of KIND ONE? Let us compare , shall we?
LIFE is who the person has been made by their earthly and heavenly nature which spontaneously and compulsively effects their culture. CULTURE is the establishment of a broad, designed end which by the force first of dictate and then, with time, tradition, hopes to seep into the nature of the individual.
LIGHT is a knowledge whose illumination functions where it was dark, your own soul. You know to what you hold fast because that was the switch you flipped that convicted you, showed you repentance and found, by its light, forgiveness. It makes all things visible to you. CREED wonders how the church will remember what is true if we don't codify it, memorize it, and chant it back to our keepers.
LOVE is generous. LAW is the tithe.
JOY cannot forget that "I am healed!". ENTERTAINMENT, acknowledges that Christians are supposed to be happy and says, "Watch this and cheer up, dammit!"
FELLOWSHIP is finding contentment with the church. FACTION is insisting on a movement.
In order to become "members of one another", KIND ONE has you sign up with them and they train you to at least wonder, if not overtly check, the membership club card of others as they enter your ecclesia. Look back over the qualities of the external "visble" church. Is it not the religion of all earthly religions? It doesn't matter that it speaks wonderfully true things about the Triune God and the work of Christ. It as if they said "We want a religion just like the nations round about but we want it to be true and bigger and better." KIND TWO considers that if you "are" Christ's you probably value what you have in Him. You recognize those that have it too.
Certainly both kinds of Christian can be deceived in false brethren. At least to fool KIND TWO Christianity, fraudulent brothers must work very hard to fake the LIFE LIGHT LOVE JOY. I know real believers who struggle with these elements of the Faith. Usually you have already lowered the bar in your own lives regarding what those mean until even a Mormon could qualify by being like the "nice, good citizen" to which you have slipped. Go back and look at how those gifts of God are expressed in the truly changed believer. Now, how hard do you think it is to fake CULTURE, CREED, LAW, and ENTERTAINMENT?
Maybe Colossians 2:16-23 will read more clearly with this distinction made.
"Therefore let no one pass judgment on you in questions of food and drink or with regard to a festival or a new moon or a sabbath. These are only a shadow of what is to come; but the substance belongs to Christ. Let no one disqualify you, insisting on self-abasement and worship of angels, taking his stand on visions, puffed up without reason by his sensuous mind, and not holding fast to the Head, from whom the whole body, nourished and knit together through its joints and ligaments, grows with a growth that is from God. If with Christ you died to the elemental spirits of the universe, why do you live as if you still belonged to the world? Why do you submit to regulations, "Do not handle, Do not taste, Do not touch" (referring to things which all perish as they are used), according to human precepts and doctrines? These have indeed an appearance of wisdom in promoting rigor of devotion and self-abasement and severity to the body, but they are of no value in checking the indulgence of the flesh."
Or Galatians 3:1-5
"O foolish Galatians! Who has bewitched you, before whose eyes Jesus Christ was publicly portrayed as crucified? Let me ask you only this: Did you receive the Spirit by works of the law, or by hearing with faith? Are you so foolish? Having begun with the Spirit, are you now ending with the flesh? Did you experience so many things in vain? -- if it really is in vain. Does he who supplies the Spirit to you and works miracles among you do so by works of the law, or by hearing with faith? "
Or if God might be more direct, Hebrews 8:6-13
"But as it is, Christ has obtained a ministry which is as much more excellent than the old as the covenant he mediates is better, since it is enacted on better promises. For if that first covenant had been faultless, there would have been no occasion for a second.
For he finds fault with them when he says:
The Oracle, stolen from St. Paul in Galatians 5:7-9,
"You were running well; who hindered you from obeying the truth?
This persuasion is not from him who calls you.
A little leaven leavens the whole lump."
