What is the spiritual meaning of Epiphany?

On the Solemnity of the Epiphany in 2019, Pope Francis said,

It is not enough to know where Jesus was born, as the scribes did, if we do not go there. It is not enough to know that Jesus was born, like Herod, if we do not encounter him. When his place becomes our place, when his time becomes our time, when his person becomes our life, then the prophecies come to fulfilment in us. Then Jesus is born within us. He becomes the living God for me. Today we are asked to imitate the Magi. They do not debate; they set out. They do not stop to look, but enter the house of Jesus. They do not put themselves at the centre, but bow down before the One who is the centre. They do not remain glued to their plans, but are prepared to take other routes. Their actions reveal a close contact with the Lord, a radical openness to him, a total engagement with him. With him, they use the language of love, the same language that Jesus, though an infant, already speaks. Indeed, the Magi go to the Lord not to receive, but to give. Let us ask ourselves this question: at Christmas did we bring gifts to Jesus for his party, or did we only exchange gifts among ourselves?
