 While Abner’s arguments regarding the Trinity and Incarnation are generally more developed in Mostradorde Justicia, the philosophical importance of this work resides with his critique of the Jewish philosopher. Here Abner distinguishes between the regular Jewish people (that have some hope to become Christian and to be saved) and Jewish philosophers (like Pulgar). The latter are hopeless and are left with no religion, mostly due to their opinions that only the people who attain scientific knowledge have some kind of existence after death. Due to their feeling elevated over others, these philosophers have no hope of improving and accepting the truth of Christianity. Parts of Abner’s critique of Jewish philosophers in this book most probably influenced Crescas.
