Query: Who felt that humanism would surely be a major "religion" today?
Context: In this polarised atmosphere, in which established ecclesiastical bodies tended to circle the wagons and reflexively oppose political and social reforms like extending the franchise, universal schooling, and the like, liberal reformers and radicals embraced the idea of Humanism as an alternative religion of humanity. The anarchist Proudhon (best known for declaring that "property is theft") used the word "humanism" to describe a "culte, déification de l’humanité" ("worship, deification of humanity") and Ernest Renan in L’avenir de la science: pensées de 1848 ("The Future of Knowledge: Thoughts on 1848") (1848–49), states: "It is my deep conviction that pure humanism will be the religion of the future, that is, the cult of all that pertains to humanity—all of life, sanctified and raised to the level of a moral value."
