Nowadays you regularly hear condemnation of this or that person or attitude for divisiveness as though to separate was intrinsically bad and to join in unity always good. You must respect those whose views are different to yours or society cannot get along, or so it goes. But here's the truth. Divisiveness is good. It is even essential if you wish to preserve truth. I don't respect falsehood, I don't respect wickedness, I don't respect anything or anybody that denies the reality of God. To condemn divisiveness is a trick of the devil to get us to accept his degenerate and corrupt agenda. We must separate good from evil, truth from lies, love from hate. But principally we must separate that which acknowledges God from that which does not. Then other things will follow. You don't love the devil and his works. You don't include them in a fatuous oneness. You reject them utterly as well as the souls that embrace them though with compassion for such souls for while you reject their error and the inner spiritual sinfulness that has led them into error, you still know them as potential sons and daughters of God if they can repent of the sins that have caused them to go astray.
Christ brought a sword, the sword that cleaves truth from lies. In that sense, he was the most divisive person who has ever lived but, at the same time, he also came to heal the division caused by the Satanic introduction of the lie. The devil seeks unity so that he may separate souls from God. Christ divides truth from the lie in order to unite souls with God on a higher plane.
I have posted this under the two tags of equality and non-duality for the former is a secular version of the latter. Both equality and non-duality see all souls as one and basically the same, but they miss the truth that true oneness can only be attained after division has done its work in separating out that which accepts God from that which rejects him. And note that the rejection of God is not just the deliberate refusal of him but also the lack of positive acceptance. There is the active denial of God and there is the more passive ignoring of him, and though the latter may be less spiritually destructive, it is still rejection. The lesson for souls in this world is not for them to realise the unity of everything in it regardless of what it is but to learn to separate good from evil and true from false. Through this separation one grows into true spiritual unity in the reality of God.
