We are not used to thinking about owing anything to God. In many ways, religion has become focused on “me,” going to Church therapeutically to feel good about oneself. In reality, we owe God everything. Religion, traditionally understood, sought to render to God the worship, homage and thanksgiving that was due to him as God, the one who made us, cares for us and saves us. In Catholic theology, this was understood as an expression of justice, rendering a debt unto God, which is fulfilled by the virtue of religion.
A virtue refers to a habitual disposition to perform a good action, so that it becomes like second nature. Religion becomes a virtue when we have a readiness and ease in giving God what we owe him.
