Perhaps today we are tempted to say: we do not want to rejoice at having been chosen, for this would be triumphalism.
It would be triumphalism to think that God had chosen me because I was so important. This would really be erroneous triumphalism.
However, being glad because God wanted me is not triumphalism. Rather, it is gratitude, and I think we should re-learn this joy: God wanted me to be born in this way, into a Catholic family, he wanted me to know Jesus from the first.
What a gift to be wanted by God so that I could know his face, so that I could know Jesus Christ, the human face of God, the human history of God in this world! Being joyful because he has chosen me to be a Catholic, to be in this Church of his, where subsistit Ecclesia unica; we should rejoice because God has given me this grace, this beauty of knowing the fullness of God’s truth, the joy of his love.
