It is widely accepted that parents have a fundamental moral obligation to consider and treat their children as each other’s equals. Yet the question of what grounds the equality of status among children in the eyes of their parents has so far been largely neglected in the literature on the philosophy of childhood and the ethics of parenthood. This paper fills this gap by developing a novel theory of the basis of filial equality: it argues that parents ought to consider and treat their children as equals by virtue of loving them. Parental love is the basis of filial equality.

In this article, I argue that God is authoritative over us because he is our divine, causal parent. As our causal parent, God has duties to relate to us, but he can only fulfil those duties if he has the practical authority to give us commands aimed at our sanctification. From ought-implies-can reasoning, I conclude that God has that authority. After I make this argument, I show how the view has significant advantages over extant arguments for divine authority and can help solve other significant problems in philosophy of religion.
