Here I am going to explain what I see as the most important philosophical departure between Christianity, in most forms I’m aware of it, and the Law of One philosophy as I believe and practice it.
The Law of One states that all is one, and that all things are the one infinite creator, i.e. God. I am further articulating my understanding of this philosophy in Winning Arguments. Other articulations of this philosophy which I appreciate can be found in the Ra material (where I learned the Law of One philosophy), and in the ascension glossary created by Lisa Renee.
I would like to compare the Law of One to the mystery/doctrine of the Holy Trinity in Christianity. According to the Holy Trinity doctrine/mystery, God is three persons in one: God the Father, God the Son Jesus Christ, and God the Holy Spirit. It is a central paradox of Trinitarian Christianity that three distinct beings can at the same time be one being, namely God.
The Law of One entails the doctrine/mystery of the Holy Trinity. The Law of One, which states that all is one, implies that everything conceivable exists and that all things are God. Therefore the Law of One implies that God, Jesus Christ, and the Holy Spirit exist and are the same being. It goes further by extending this identity to everything. The mystery/doctrine of three distinct and identical forms of God is subsumed by the mystery/doctrine of infinite, all-encompassing distinct and identical forms of God.
The Law of One importantly negates the distinction, important to most forms of Christianity, between forms of God and forms that are below God. Christianity acknowledges three forms of God, and an incredible multiplicity of forms below God. According to the Law of One, all forms are forms of God. This mystery/doctrine implies that even the most profane thing is holy.
Of course, the Law of One is paradoxical. The Trinity is paradoxical too, in the same way. Both mysteries/doctrines say that some distinct things are identical. Both mysteries/doctrines contain a logical contradiction, which by the rules of classical logic, allows one to infer that every statement is both true and false. In short, both doctrines have an incompatibility with classical logic, because it is incompatible with classical logic to say that multiple distinct things are perfectly identical.
One may argue that the Law of One’s contradictions are more problematic, because they extend to everything, rather than just three things. A Christian might retort that while the paradoxes of the Trinity apply only to three things, those are the most important things that exist, meaning that the paradoxes of the Trinity are not much less important for extending to fewer things. However, the Law of One’s contradictions might be thought to create more practical problems, since they extend to the world of practical things as well as spiritual things.
I go into this topic much more in Winning Arguments. In the section titled Paradoxes, I have a practical solution to logical paradoxes, based on defining, defending, and justifying the practice that people already employ of rejecting proofs of logical contradictions on an ad hoc basis.
In the section of Winning Arguments titled The Law of One, I am working on a philosophical, theological, and metaphysical route to solving paradoxes, to complement and supplement the practical approach in the section titled Paradoxes.
The hope is to provide an intuitively satisfying solution to the paradoxes which makes a world with paradoxes make sense, as closely as I can attain to such a goal. It’s my opinion that perfectly comprehending the paradoxical mysteries/doctrines of the Law of One and the Trinity is beyond the intelligence of humans. I am merely working to do my personal best at the problem.
I have articulated the abstract difference of opinion between the doctrine/mystery of the Trinity and the doctrine/mystery of the Law of One. I think there are a lot of more concrete differences of opinion that can flow from this key difference of opinion between the Law of One philosophy as I believe and practice it, and most forms of Christianity I’m aware of.
For me the most important of these concrete differences have to do with the attitude towards the self and the attitude towards God.
Most forms of Christianity I’m aware of encourage the worship of God in the form of Jesus Christ as envisioned by the practitioner (often in the likely inaccurate form of a white male). They encourage a sense of the dependence of the self on God and the powerlessness of the self relative to God.
These attitudes, in my opinion, are basically accurate. I think that we as humans are dependent on God and relatively powerless compared to God. These are facts about the world as I see it. Here I am understanding God as the infinite intelligence which is the unity of all things. But I think there is an important truth missing from the previous paragraph, namely that each of us is God. Being God, each of us is potentially as powerful as any part/form of God. The judgment that we and all others are God has many implications for our relationships to ourselves, to others, and to God.
How does believing that I am God affect my relationship to myself? It creates a moral imperative to hold myself in very high regard. This is balanced by the belief that others are God, which creates an analogous moral imperative to hold others in very high regard. There is an imperative not to resonate with disrespect of oneself by the self or others, and an imperative to afford others the same respect one feels entitled to. All of these attitudes, of course, are quite popular, independently of the Law of One.
For me, years of looking into the meaning of respecting oneself and respecting others have felt very informative in exploring the mystery of how to behave morally in the world. This journey goes on for me, as I think it does for us all.
These attitudes toward the self and others come into conflict with various forms of Christianity.
They come into conflict with authoritarian attitudes towards doctrine, where individuals are told to understand God’s truth through the word of authority as opposed to their own intellectual, moral, intuitive, and spiritual discernment.
They come into conflict with forms of Christianity which have the effect of hobbling people with the psychological slavery of guilt and self-hatred. The Law of One teaches what I would call “master mentality,” which can be contrasted with “slave mentality.”
Master mentality. I like all others, am the master of my choices. No others can tell me what choices to make unless I consent to be ruled by them in this way. All of my allegiances are chosen by me based on my personal discernment that they are good from my perspective.
Slave mentality. Some others are my only proper masters, or God, who is a person separate from me, is my only proper master. I cannot trust myself to steer my life for myself. I should submit unquestioningly to some authority in order to lead an upright life.
Slave mentality is a point of view that is hard to reconcile with the understanding of oneself as God. To be God is to be sovereign and free. To be God is to be ruled by no higher master than oneself. Since I regard those with slave mentality as God, I am of the opinion that they are choosing their slave mentality; but I think most people with slave mentality don’t see themselves as having any proper choice in the matter.
I think slave mentality is usually rooted in fear. For example: believing the doctrine of one’s church for fear of being ostracized from one’s church; following or not challenging a dominant political ideology for fear of being ostractized or attacked by its supporters; shying away from master mentality because one fears the potential of one’s power or what one would do with a mind liberated in that particular fashion; etc.
I am not saying that slave mentality is wrong for everybody. The people who choose it have reasons for their choices. I am saying that believing “I am God” naturally leads to master mentality, and that slave mentality is hard to reconcile with believing “I am God.”
I am not saying that master mentality is always a good thing. Clearly many people who have regarded themselves as masters of themselves have gone on to do very evil things on that basis. In my view, master mentality is, generally speaking, a good thing in the context of a philosophy aimed at service to others, and built on a recognition of the weighty moral responsibility entailed in holding oneself God, sovereign, and free.
Trinitarianism does not necessarily lead to slave mentality. I think one can believe that God is three persons in one, the Father, the Son, and the Holy Spirit, and that these are the only forms of God in existence, while also seeing oneself as master of oneself.
However, I do think that Christianity as I’ve observed it, and I would say most institutions of Western culture, trend towards encouragement of slave mentality and discouragement of master mentality. I attribute this, in the case of Christianity, in part to the observation that Christianity as we have it today in the West is almost all derived from the Catholic church, even if by way of the Protestant traditions, and that the Catholic church, as an organized system of social and political control, has always had a lot to gain from inculcating slave mentality in people.
More generally, all organized systems of social and political control benefit from inculcating slave mentality in the general public. Why? A population infected with slave mentality is much easier to control. In contrast, a population infected with master mentality is much harder to control. Slave mentality keeps master mentality safely at bay. I think that we can see the inculcation of slave mentality by those in control basically anywhere we look in history.
As such, I am inclined to see slave mentality in general as a kind of mental parasite, whose purpose is not to help its host, but whose usual purpose is to help some force in the social universe which is getting power over the host by manipulating their mentality.
These are some of the reasons why I am getting over my own fear of adopting master mentality, which is rooted in fear of myself stoked throughout my life by those who wish to inculcate a slave mentality in me. I don’t have time for that.
 The Law of One implies that all conceivable things exist because it implies that every statement is true. One way of reaching this conclusion is as follows. Assume the Law of One is true, let A be any statement, and let B be any true statement. According to the Law of One, all is God. Therefore, A is God, and B is God. Therefore, by the transitive property of equality, A is B. Since B is true and A is B, A is true.
 Jesus is said to have lived in the Middle East, where most people today have brown skin.
