" The Christian psychologist often sound Christian and biblical . Many of the theological words are there. But the meanings are different. The current mass psychologization of Christian life and thought is the popular fruit of the integration movement. The logic and drift of the integrationist movement has not been biblical logic and drift. The church is reaping the consequences. Integration or inundation? The deluge is upon us. If Machen wrote his book today, he would entitle it Christianity and Psychologism. The modern psychological evangelicalism, the intellectual flood in which we float or against which we swim, is not Christianity. "
