This church is characterized, not by any definite evil either of doctrine or practice, but by pride of acquirement and by self-sufficiency, accompanied with indifference to Christ. While boasting itself in being rich and in need of nothing, it was wretched, miserable, poor, blind, and naked. Man in his self-satisfaction is the main feature, and Christ is not appreciated. It represents the arrogance of rationalism and higher criticism in the latter days of the church on earth. Christ is outside but still appealing, knocking for admission to the individual heart.
