I like reading Art Katz, Watchman Nee, Oswald Chambers, et cetera, but is that wrong, since it's "extrabiblical" in some sense? I find them hugely inspiration, but am I replacing the Word with them?
Often, the answers are in our own questions, which reveal how we have been taught to think, or, asked to start thinking by someone else presenting their own point of view, as you have been in this situation.
Regarding your friend only reading the word of God, that is slightly similar to my having decided many years ago, only to sing for God. (No pop music for 'fun', or taking up my brainspace with secular words.) If God said that to your friend, which I can believe He did, then your friend has no choice any more.
But, if God has NOT told you only to read the word, then you do have a choice, still. Why? Because God wants you to learn to walk in newness of life, making your choices through the Spirit's leading.
Romans 8 TNT
For they that are carnal, are canally minded. But they that are spiritual, are ghostly minded. To be carnally minded, is death. But to be spiritually minded is life and peace. Because that the fleshly mind is enmity against God: for it is not obedient to the law of God, neither can be. So then they that are given to the flesh, cannot please God.
But ye are not given to the flesh, but to the spirit: if so be that the spirit of God dwell in you. If there be any man that hath not the spirit of Christ, the same is none of his. If Christ be in you, the body is dead because of sin: but the spirit is life for righteousness' sake. Wherefore if the spirit of him that raised up Jesus from death, dwell in you: even he that raised up Christ from death, shall quicken your mortal bodies, because that this spirit dwelleth in you.
Therfore brethren we are now debtors, not to the flesh, to live after the flesh. For if ye live after the flesh, ye must die. But if ye mortify the deeds of the body, by the help of the spirit, ye shall live. For as many as are led by the spirit of God: they are the sons of God. For ye have not receivd the spirit of bondage to fear any more, but ye have received the the spirit of adoption whereby we cry Abba father.
So, in pitting people like Katz, Nee and Chambers against the word of God, you are almost setting up a false controversy. The question would be entirely different if you were asking whether you should give equal time to reading ancient philosophers, or murder mysteries, as to wholesome spiritual reading.
However, as has been pointed out, even Paul had studied the literature of his day, before he was born again. This gave him a point of contact with not only the greatest he would encounter, but with the ordinary educated man or woman.
The difference in his thinking after he was born again, was stark, in that the disciplines he recommends were not there as some new laws, but as good advice on cultivating the life of God and being renewed in the spirit of our minds. The advice he gave is universally applicable, and covers anything important which we meet today.
Your challenge, then, is to turn this into practical Christian living. If the Holy Spirit gives you permission to read Aristotle, do it with all your heart to the Lord. This isn't a silly suggestion, as you have a good mind, and Augustine based some of his choices on Aristotle's thinking (or not). One of the things most lacking in this generation, is classically educated thinkers who can read the word of God and see all the writers challenging philosophy, some of which greatly affects our age.
But, if the Holy Spirit tells you to read scripture only for six months, you better do that too, with all your heart, unto the Lord....
See what I mean? ;-) It's a challenge - to [u]walk[/u] in the Spirit.
