We look to Joseph as the model educator, who watches over and accompanies Jesus as he grows “in wisdom, age and grace,” as the Gospel says.
Let us begin with age, which is the most natural dimension, physical and psychological growth. Joseph together with Mary, cared for Jesus above all from this point of view, that is he “raised” him, taking care that he lacked nothing he needed for healthy development…
In those years Joseph instructed Jesus in his work, and Jesus learned to be a carpenter with his father Joseph. Thus Joseph raised Jesus.
Let us move to the second dimension of his education: “wisdom.” Joseph was for Jesus the example and the teacher of the wisdom that is nourished by the Word of God. We could ponder how Joseph formed the little Jesus to listen to the Sacred Scriptures, above all by accompanying him on Saturday to the Synagogue in Nazareth.
And lastly, the dimension of “grace”… It would be a grave error to think that a father and mother can do nothing to form their child to grow in the grace of God. To grow in age, to grow in wisdom and to grow in grace: this is the work Joseph did with Jesus, to help him grow in these three ways, to aid his growth.
