So, really, you’d need to start off with ‘what’s Judaism all about?’ sorts of questions and move on from there. Places like
Judaism 101 might be helpful.
I concur with Kaninchen, and add that if you are Catholic you must do even more than merely learn about Judaism from the source, but do as the Church now teaches:
learn about Judaism and be actively engaged in building bridges, not walls, between.
Especially since St. Pope John Paul II, through the papacy of Benedict XVI and now today with Pope Francis, the Vatican as well as local bishops conferences (like the USCCB) are encouraging all Catholics to walk with the Church in its current understanding of
Jewish-Christian dialogue and relations.
You will want to read “
The Gifts and Calling of God Are Irrevocable,” recently released on the Vatican website. And you will want to take seriously how much the Christian faith stands to gain from this precious relationship with our elder brethren of Judaism.
A recent example: “The most important thing we can learn from the Jewish people is first of all it’s a religion not of the synagogue but of the home, the family,” Cardinal Kurt Koch, President of the Commission of the Holy See for Religious Relations with the Jews
recently stated. Christianity can only flourish by learning from our Jewish brethren, a faith “rooted in the family” and the “clear tradition of Shabbat….Family and Shabbat are two main challenges for Christianity,” noted the Cardinal, and that the Sunday “culture in Christianity is very weak.” There are so many gifts in Judaism that have just never been properly appreciated by Christians that can only aid us in serving God if we but listen.
Learning from the Jewish example can’t be done merely by looking up websites or reading books. They are great starts, yes, but you need to become involved in the Catholic-Jewish dialogue on the local level. You might want to begin by learning if there are any Hebrew Catholics in your parish or area. Some of these Hebrew Catholics still have strong connections with their Jewish family members and rabbis, and some occasionally still visit their synagogue or temple communities as guests. Some may even be involved in the actual official dialogue between the two great faiths as well and can thus introduce you to other Catholics and Jews who can help you learn firsthand about Judaism.
In the end, it has to be far more than what you think Judaism gets right or wrong or where Catholicism might be lacking or has things right. It has to be about allowing both sides to speak in such a way that shared values and God’s providence can speak for itself as it shines through from both. The recent Jewish
Orthodox Rabbinic Statement on Christianity is but one of many examples how things have and are changing in the way Jews and Christians view one another.
There will be some on both sides who might still prefer building walls and living behind them in this regard, but as Catholics our duty is to build and cross these bridges and actively extend our hands to those who are extending their hands to us.
