"Humility is the door, honesty is the way, and spirituality is the summit." (MBE in CCT, Eustace)
Humility is the door. Post-modernism, socialism, cultural marxism, etc., slam the door on humility because they make man God, in the sense that they look no further than themselves for wisdom, guidance and morality. As these have infiltrated the educational systems, including seminaries, humility has been usurped by self-important moral superiority and intolerance, "my way or the highway," ironically the same downfall as institutional religion. But Christ Jesus set the gold standard of humility when he said, "Of mine own self I can do nothing. The Father that dwelleth in me, He doeth the works."
Honesty is the way. When honesty is to one's own convictions, when those convictions are based upon an 'ism, self-justification is the result. But when honesty follows the humility defined by Jesus, this statement applies: "Honesty is spiritual power. Dishonesty is human weakness which forfeits divine power. " (S&H)
Spirituality is the summit. The spirituality referred to here in no way resembles the worldly spirituality which is so popular among the New Age folks and others. But here spirituality has to do with Spirit, God, and nothing less.
In this context, perhaps Christianity is not waning in the West, but rather it is going through a purification process:
"Spirituality is the only Christianity; and its basis is, 'to be absent from the body and present with the Lord;' sensuality is personality ever present with the body. We have already sufficient professions of goodness without the Spirit: too many religions and not enough Christianity is the genius of the age. Man knows already too well how 'to make long prayers, to be heard for his much speaking,' and to enlarge the Pharisaical borders, to steal in private and give in public, but this is political, not Christian economy. What we want is, 'Christ and Him crucified,' in other words, Truth and the cross-bearing that attends it, to make mankind better."
