The eschatological presuppositions of both HuvB & Maritain lead implicitly & inevitably to apokatastasis. Neither of their (pious but ad hoc) attempts to variously stop short of same, in my view, can successfully escape their own logic.
The presuppositions of Balthasar’s universalist hope lead to an indicative – not subjunctive – universalism, for his critique of the antecedent & consequent wills distinction leads inevitably to the former, as he’s thereby inchoately anticipated & adopted DBH‘s game theory analysis.
The presuppositions of Maritain’s eschatology lead to – not only apokatastenai, but – apokatastasis, for his admission of miraculous interventions in the ordinary rules of being, also, leads inevitably to the reversibility of rejections of grace.
Is there no basis in tradition for Maritain’s theory, which Balthasar himself propounded?

The above represent – not Brotherton’s conclusions, but – my thoughts after reflecting on Joshua R. Brotherton’s article in Theological Studies, vol. 76, 4: pp. 718-741. November 30, 2015.
As Royce’s concrete Absolute modified Peirce’s semeiotic; Aurobindo’s integral Absolute modified Advaita; so Maximus’ Logos-logoi identity modified Neoplatonism. In each case, the concept of the Absolute became both concrete & social?
