Over the past couple of months, I have been receiving emails explaining the Parsha which I understand is the weekly Sabbath reading for the Jews.
Aside from giving me more knowledge of the Torah (the Pentateuch, the first five books in the Old Testament, often referred to in Scripture simply as "Moses"), I am being introduced to the Talmud, for which I don't think a Christian counterpart exists. Maybe the Catholic Catechism and the Code of Canon Law, but don't quote me on that!
It is very interesting.
What is most evident to me is just how rooted in history are the liturgical practices of Christianity, at least as found in Catholicism (of which I have the most experience). Communal study of Scripture on the Sabbath is to be made available to Jewish communities. They are restricted from many activities. Catholics are reasonably required to attend Mass (which is a type of Scripture study...plus so much more!) on all Sundays and Days of Obligation. They are also to refrain from unnecessary labour. Jews have restrictions on what they may or may not eat. Catholics are asked to fast and abstain from time to time, and the elements that go into the confection of the Eucharist, are very clearly defined.
From another source I learn that the materials to be used in Jewish worship, such as the garments the rabbi wears, are to be of the best materials. A similar admonishment is found in Catholic liturgical documentation, as well, with regards to the materials used in the Sanctuary and during Mass
It amazes me that some are so quick to dismiss some practices of Catholicism as being wasteful, elitist, imperialistic, impractical, extravagant etc. when there is such base for these practices in Judaism, from which we sprout.
