Of God and His Creatures

This would emphasise the pronoun, to give TO YOU. Unfortunately that pronoun is absent in the Greek, which may be rendered: It is not mine to give: it is only for them for whom it is prepared. We may perhaps accommodate St Thomas thus: 'It is not in my power to give on the title on which it is asked,' -- namely the title of personal friendship and family connexion.
