There are many ideas put forward as solutions to the crisis of the modern world (not Covid 19, that's just an element, albeit an important one, of something much larger), political, ideological, even spiritual of sundry sorts. But they all lack overall coherence. However, there is something that stands above them all which reconciles any good there might be in them at a higher level without including the dross, illusion and bad qualities they all contain without this thing. It can be summed up in a sentence.
That sentence is Matthew 12:30. "He that is not with me is against me". This pithy injunction means if you are not actively for the truth of Christ, you are against it. Not passively against it, actively so. According to this saying, there is no middle ground. If you are not for Christ, you oppose him. Neutrality is not an option.
This might seem unreasonable. Why, if you don't accept Christ, does that mean you are the enemy of Christ? Why can you not be a good, upstanding, morally decent person without acknowledging Christ?
You can't because Christ is the embodiment of truth and if you don't recognise that then you don't recognise truth in which case you will be on the outside of truth, working against it whether that be in a greater or lesser sense. Christ is like magnetic north. If the lodestone of your being does not point to him then it is broken. You are broken. Your soul is sick.
These may sound harsh words but what they amount to is this. You want to be good. You may think you are good according to the standards of the world. But those standards are false standards because they do not recognise the reality of what this world is; that it is not justified in and for itself and human beings do not exist for the fulfilment of what they appear to be in the light of this world. You want to be good but you don't acknowledge what good is for it is summed up in Christ and his teachings.
And here's the strange thing, something that goes right to the metaphysical roots of life. You might think you can be good without Christ, and perhaps you could be if the fundamental reality of life were abstract principle, something like pure being. But it is not. God is love. Life is ultimately personal. Truth is a person not a thing and that person is revealed for us in Christ.
So these are not harsh words. They are simply true words because they point to the reality of what life is. If you do not recognise Christ, you are rejecting real truth and goodness and replacing the genuine source of these things with some kind of idol. A person who thinks he can be a good person on his own without Christ is an idol worshipper and whether that idol be his own self or some kind of philosophical ideal makes little difference in the end. He is still substituting a false reality for the truth and he is doing that because of a spiritual falseness within himself. Christ is the truth and if you don't know that you don't accept truth, and if you don't accept truth, well then, you reject it.
The only exception to this rule I can think of applies to people who have not been made properly aware of Christ but who follow his closest approximation in another religion. I believe that after the Incarnation the spirit of Christ was spread across the globe and did influence other religions through forms in them that could accommodate that spirit such as the Bodhisattva ideal in Mahayana Buddhism. That is a secondary thing to knowing Christ in himself but in this case if the spirit of any religion has absorbed something of the Christ influence, the Universal Christ you might call it, then people of true heart can follow the pattern of Christ as it is manifested in their own religion. This does not apply to modern secular substitutes, however, which are based on the rejection of the transcendent reality of Christ. Christ can manifest through a religion other than Christianity if the spirit of that religion is open to him but not through something that denies not only his form but his very spirit.
The converse to this is those professed Christians who nevertheless do not follow the spiritual reality of Christ, who perhaps are external Christians only, people for whom the trappings of religion, the lamp, is more important than its inner reality, the light. These are the people spoken of by Christ when he said in another text from Matthew, this time 7:21, "Not everyone who says to me 'Lord, Lord' will enter the kingdom of heaven, but only he who does the will of my Father in heaven". For Christ has an outer aspect and an inner aspect and only those who dedicate themselves to the truth of the inner aspect are really with him. To be for Christ means to put the reality of Christ, the spiritual reality, above everything else, at all times and in all circumstances. If you are not for him, you are against him.
The Good is spiritual. If your conception of the good is material only, supporting people as they are in this world with no understanding of the needs and destined purpose of the soul, then you are effectively standing against the true good which means you are doing spiritual harm whether that is your intention or not. Christ taught that his kingdom was not of this world but that does not mean that the world should not fall into line with the truth of Christ. It means that the truth of Christ can never fall into line with this world. If there is anything in this world that for you comes before Christ then you are not with him.
