Pope Francis made an interesting comment in his Pentecost homily:
A Christian without memory is not a true Christian. He is only half Christian, he is a man or a woman who is a prisoner of the moment, who does not see his or her history as a treasure, does not know how to read it or live it as history of salvation. But with the help of the Holy Spirit, we can interpret the interior inspirations and events of life in the light of Jesus’ words. And, thus, there grows in us the wisdom of memory, the wisdom of the heart, which is a gift of the Spirit. May the Spirit revive the Christian memory in each us! And that day, with the Apostles, was the Woman of memory, she who from the beginning meditated on all those things in her heart. It was Mary, our Mother. May she help us along this road of memory. The Holy Spirit teaches us, reminds us, and – another thing – he makes us speak, with God and with men. We are not mute Christians, mute of soul; no, there is no room for this.
Go here to read the rest. Since Vatican II, too many Catholics have become bone ignorant as to the history of the Faith, making themselves, and too often the Church, a prisoner of the moment.
