The differences of nature, reaction, viewpoint, and thinking between men and women, far from occasioning concern, should be regarded as highly beneficial to mankind, both individually and collectively. Such dual associations greatly multiply versatility and overcome inherent limitations. 
Without co-ordinate existences there is no possibility for the appearance of diversity of absolute relationships, no chance for the operation of differentials, variables, modifiers, attenuators, qualifiers, or diminishers.  While infinity is on the one hand UNITY, on the other it is DIVERSITY without end or limit.  Although the universe may present many problems and situations which apparently portray disharmony, unity underlies creative diversity. 
Mind is unifying of all divergencies, but in the very absence of such divergencies, mind finds no basis upon which to attempt to formulate understanding concepts. 
One positive aspect of diversification of races is that stimulate healthful competition. 
The evolution of six —or of three— colored races, while seeming to deteriorate the original endowment of the red man, provides certain very desirable variations in mortal types and affords an otherwise unattainable expression of diverse human potentials. 
Each of the apostolic teachers taught his own view of the gospel of the kingdom. Jesus upheld this presentation of the diversity of personal experience in the things of the kingdom.  Do not forbid the strange preacher to proclaim the gospel of the kingdom. He who is not against us is for us. 
A prophet named Kirmet created a considerable ruckus in the camp of believers, and Simon Zelotes was in favor of dealing rather roughly with the self-deceived pretender, but Jesus intervened and allowed him entire freedom of action for a few days.  Jesus constantly exhorted them to refrain from trying to mold the disciples and believers according to some set pattern. 
Religion of spirit permits diversity of belief, and allows to enjoy a profound spiritual unity in the very face of the utmost diversity of individual attitudes.  The kingdom of heaven in the hearts of men will create religious unity.
