I recently was able to attend Messianic Jewish services on a Saturday morning and was astonished at how much of our Catholic rituals I found in theirs. I realize they are separated brethren, but in some ways they are far LESS separated than many mainline Protestants I know of. I agree with the earlier poster, regarding several of our traditions being completed or fulfilled versions of their Jewish ones.
They had a tabernacle (HUGE!) centered on their altar, complete with a veil inside, and opening it up was a big deal. Inside was the Word of God (the Torah), and their scrolls include the entire Bible (well, almost, only 66 books) Once the Torah has been removed, they carried about the room and everyone touched it and then touched their lips to remind us all to always have the Word of God on our mouths. Then it was brought to the front and carefully placed on their ambo for the readings. I loved the thought of Jesus, in the Catholic tradition of the Blessed Sacrament, being carried about the room during Benediction. It was a clear connection to me.
They had an ambo, only it was gigantic, to hold the Scriptures and read from them. There were two readings and then a homily, which was quite long but very very good. They had a credence table on which the bread and wine were held during the services, and they even used the words “fruit of the vine and work of human hands…” when blessing it, though of course they did not consecrate it. And everyone ate the bread, though only the man who did the blessing drank the wine. Some of them wore yarmulkes and some wore prayer shawls and tallith. But not everyone. It was a fascinating experience and we felt both welcomed and comfortable, though of course we could not participate in their “communion” service, such as it was.
Our Messianic Jewish friends were also recently invited to a Catholic wedding, complete with a Mass, and said they were so comfortable there and recognized so much of what they are accustomed to in their own services.
