Saint Monica
Augustine turned away from Christianity to other ethical approaches, a moral apostasy even if not yet baptized. St Monica prayed for decades for his conversion and was eventually rewarded. Likewise the Pharisees knew the Torah but followed the outward rules (cardinal virtues) meticulously and ignored or turned from the heart virtues, the theological virtues. The result was the destruction of Judaism. We see the same in the world today, the outward , an outward talk about justice and rights and even Christian trappings, but no inward heart commitment to be like Jesus and his Father, no submission. And we can be drawn into this too. So ask St Monica to pray for you and St Augustine to show you what it looks like to keep turning our hearts to God, so we will enjoy the fate of the saints and not that of the Pharisees (or the French Revolution).
