 First of all, the Christians are not required to maintain the belief in the Trinity except that it is necessary for belief in the Incarnation of God in human form because of the attribute “Son” which creates particulars in the existence, as has been explained. For without this, neither the immortality of the soul after death nor their receipt of reward and punishment in the world to come could be established. In this way the Torah, which gives existence and permanence to the existence of the human species and individual personalities according to what is possible, is established. Furthermore, as I proved above, the beliefs which cause the performance of the commandments are (the ones which are) incumbent upon us to believe in. (Teshuvot la-Meḥaref: 21b)
