Another unity is the spiritual unity which emanates from the breaths of the Holy Spirit. This is greater than the unity of mankind. Human unity or solidarity may be likened to the body whereas unity from the breaths of the Holy Spirit is the spirit animating the body. This is a perfect unity. It creates such a condition in mankind that each one will make sacrifices for the other and the utmost desire will be to forfeit life and all that pertains to it in behalf of another's good. This is the unity which existed among the disciples of His Holiness Jesus Christ and bound together the prophets and holy souls of the past. …. This unity is the very spirit of the body of the world. It is impossible for the body of the world to become quickened with life without its vivification. His Holiness Jesus Christ -- may my life be a sacrifice to Him! -- promulgated this unity among mankind. Every soul who believed in Jesus Christ became revivified and resuscitated through this spirit, attained to the zenith of eternal glory, realized the life everlasting, experienced the second birth and rose to the acme of good fortune.
