CCC 268 Of all the divine attributes, only God’s omnipotence is named in the Creed: to confess this power has great bearing on our lives. We believe that his might is universal, for God who created everything also rules everything and can do everything. God’s power is loving, for he is our Father, and mysterious, for only faith can discern it when it “is made perfect in weakness”.1

CCC 273 Only faith can embrace the mysterious ways of God’s almighty power. This faith glories in its weaknesses in order to draw to itself Christ’s power.2 The Virgin Mary is the supreme model of this faith, for she believed that “nothing will be impossible with God”, and was able to magnify the Lord: “For he who is mighty has done great things for me, and holy is his name.”3

CCC 1508 The Holy Spirit gives to some a special charism of healing4 so as to make manifest the power of the grace of the risen Lord. But even the most intense prayers do not always obtain the healing of all illnesses. Thus St. Paul must learn from the Lord that “my grace is sufficient for you, for my power is made perfect in weakness,” and that the sufferings to be endured can mean that “in my flesh I complete what is lacking in Christ’s afflictions for the sake of his Body, that is, the Church.”5
