Hi Caleb -
He’s on the list as ‘Solovyov’ - his name can be spelt either way. Yes he was a universalist - he doesn’t argue for it, he just assumes it because his idea of humanity means every human being and ‘theosis’ means the transforming sanctification of humanity rather than just the individual.
Here’s a not I have on him (not sure where it comes form)
Solovyov strongly defended the concept of universal salvation, which was after all implicit in his overriding idea of the restoration of unity-of-all at the end of the world historic process. Indeed, the concept of personal salvation was totally incompatible with his metaphysics. Solovyov thought of humanity in purely social terms, and went so far as to refuse to recognize any essential opposition between the individual and society: a person was "only the meeting point of an infinite number of relations with other individuals." Since human beings were profoundly social, “the final end of their efforts, is not found in personal destiny, but in the social destinies of mankind as a whole.” Solovyov therefore denied that “individual souls alone could and ought to be saved,” because this implied the abandonment of the basic Christian task of transforming all human life into the Kingdom of God.
He was a lifelong opponent of Russian anti-Semitism and wrote in 1890 that -
‘The increased awakening of ethnic and religious enmity, so contrary to the spirit of Christianity, suppresses the feeling of justice and humaneness, demoralizes society at its root and can lead to moral anarchy, especially in view of the already noticeable collapse of humanitarian ideas and the weakness of the juridical principle in our lives. This is why, if acting only out of a feeling for national self-preservation, it is necessary to emphatically condemn the anti-Semite movement, not only as immoral in its essence, but as extremely dangerous for the future of Russia’
