However, this is an integrative approach nevertheless, i.e., mixing secular psychology with the Bible, which is an oxymoron and a slap in the face of God.
God hates mixtures of His Word with man's wisdom.
See: Jacob Prasch article at Moriel Ministries about mixtures that God hates:
Quote from above:
"In an age where pop psychology is masquerading as biblical doctrine things can become very confusing. Today we hear so much about things being a mixture of truth and error, or carnal and spiritual, good and bad, or even godly and demonic. To make matters worse, we are too often being given mixed signals. Instead of giving a clear indication of what the signals actually mean so many of our pastors and once respected leaders are now telling us things like "the light is neither red nor green but amber" - leaving us suspended in a limbo not knowing whether to go or to stop. Arriving at a right doctrinal position and discerning things in a biblical manner in times like this has become more and more difficult for many sincere believers genuinely wanting to know the truth so as to do what is right. But in an increasingly complexed maze like this, the first and foremost question is to ask "What does God say about mixture in his word?" "
2 Corinthians 6:14-18 MKJV
(14) Do not be unequally yoked together with unbelievers; for what fellowship does righteousness have with lawlessness? And what partnership does light have with darkness?
(15) And what agreement does Christ have with Belial? Or what part does a believer have with an unbeliever?
(16) And what agreement does a temple of God have with idols? For you are the temple of the living God, as God has said, “I will dwell in them and walk among them; and I will be their God, and they shall be My people.”
(17) Therefore come out from among them and be separated, says the Lord, and do not touch the unclean thing. And I will receive you
(18) and I will be a Father to you, and you shall be My sons and daughters, says the Lord Almighty.
Deuteronomy 22:9-11-Mixture Forbidden:
9 "You shall not sow your vineyard with different kinds of seed, lest the yield of the seed which you have sown and the fruit of your vineyard be defiled.
10 "You shall not plow with an ox and a donkey together.
11 "You shall not wear a garment of different sorts, such as wool and linen mixed together.
Lev. 19:19 You are to keep My statutes. You shall not breed together two kinds of your cattle; you shall not sow your field with two kinds of seed, nor wear a garment upon you of two kinds of material mixed together.
In other words, God hates mixture, and wants us to avoid it even in insignificant ways. Why? Because little compromises always end up leading to worse compromises.
Does God really care if you plow with an ox and a donkey together? Yes, because they are quite literally unequally yoked. In the same way, God hates it when a believer yokes together with an unbeliever:
2Cor. 6:14-16 Do not be bound together with unbelievers; for what partnership have righteousness and lawlessness, or what fellowship has light with darkness? Or what harmony has Christ with Belial, or what has a believer in common with an unbeliever? Or what agreement has the temple of God with idols?...
Does God really care when a garment is made of two materials? He seems to, especially considering that he wants us to be the same, cut from the same cloth. He hates it when people bless and curse with the same mouth.
James 3:9-10 With it we bless our Lord and Father, and with it we curse men, who have been made in the likeness of God; from the same mouth come both blessing and cursing. My brethren, these things ought not to be this way.
Does God really care about breeding two kinds of cattle? It would seem so, since He definitely hates it when people combine Christianity with paganism:
1Cor. 10:21 You cannot drink the cup of the Lord and the cup of demons; you cannot partake of the table of the Lord and the table of demons.
Is two kinds of seed being sown really that big of a deal? I don't know, but I do know that God hates it when people attempt to pursue Him and money simultaneously:
Matt. 6:24 "No one can serve two masters; for either he will hate the one and love the other, or he will be devoted to one and despise the other. You cannot serve God and wealth."
When you mix, you get corruption. Take for example when you mix hot and cold. What do you get? Lukewarm.
Rev. 3:15-16 "I know your deeds, that you are neither cold nor hot; I wish that you were cold or hot. So because you are lukewarm, and neither hot nor cold, I will spit you out of My mouth."
God wants our lives to be marked by holiness and oneness, not mixture.
Richard Bennett of Berean Beacon www.bereanbeacon.org, describes how the churches are filled with counseling using psychological methodologies mixed with secular business models and practices, modeled after the Catholic philosophy and theology of adding to the Bible with salvation by works based on the concept that the Word of God is "incomplete and/or inadequate" to demands of the modern era and the types of problems people encounter today:
