"...faith, hope, and love" (1 Cor. 13:13).
Christians who are baptized in the name of the Father and of the Son and of the Holy Spirit know also another holy trinity: faith, hope, and love.
The two trinities live in much the same way. We know from the Bible and theology that the Father "begets" the Son, and that the Holy Spirit "proceeds" from the Father and the Son. So too, faith begets hope, and love proceeds from faith and hope. Paul put them in exactly the right order, because where there is faith, there is hope, and where there are faith and hope, there is love.
Father, Son, and Spirit are the Three Persons of the One God. Faith, hope, and love are the three virtues of the one Christian heart.
Faith, hope, and love are given to us by God. Is it any wonder then that they have a trinitarian character? Yes, it is full of wonder!
Now remember your Baptism, the Holy Trinity, and the other holy trinity too. Nothing more is needed.
