Temptations that incite us toward evil originate from our fallen nature, our fallen world, and the devil. As a necessary consequence of free will, they have the potential to cause spiritual death by inviting us to sin. Trials, on the other hand, can lead us to spiritual life by strengthening our faith and virtue. When we turn lovingly toward God, He provides us with sufficient grace to endure all of our struggles.
Our Christian teaching supplements the four cardinal virtues with the three theological virtues of faith, hope, and charity (or love). These theological virtues elevate and perfect our habits, thus directing us toward the supernatural happiness that can only be achieved by our union with God. Theological virtues are infused in our souls through God’s gift of sanctifying grace.
The cardinal virtues are the four moral virtues thought by ancient philosophers to form all other virtues acquired by human effort and repetition. The concept of these virtues–consisting of prudence, justice, fortitude, and temperance–traces back to Plato. Saint Ambrose later assigned the designation “cardinal,” stemming from the Latin root “cardo” or hinge, to emphasize that on these qualities hinge the moral life.
In the spiritual battle of good versus evil, virtue is our armor to guard against the temptation of vice. Virtues are rooted in the healthy habits that allow us to readily discern and freely seek that which is good. While virtuous habits promote our disposition of love, habits of vice demonstrate our failure to love.
