Greetings in that Divine and Most Precious Name of Our Lord and Savior Jesus Christ!
Is there a christian church who still keep most parts of the jewish liturgy but still celebrate a christian liturgy? Do they even worship in synagouges instead of churches?
I mean, most of the christian churches did actually throw away most of the jewish tradition.
What do you mean exactly? Are you asking if there are any jurisdictions of Orthodox that practice a near verbatim service of the Jewish liturgies? Which Jewish liturgies are you referring to exactly? I am not familiar..
A little background info though:
Many Orthodox jurisdictions follow the same kinds of worship that was common in the early Jewish liturgies, including the separation of the congregation by gender, the exultation of the Gospels (similar to the Torah), the celebrating Priest standing with back turned towards the people facing the same direction as them. We also chant the Psalter in a similar manner, as well as other similar litanies, benedictions, and absolutions which come perhaps from our mutual origins. A lot of the structure and flow of the Christian liturgy is also very similar to the Jewish liturgies, and even similar melodies and intonations.
Remember, the Bible is not a book, in the original Jewish tradition the Bible was more so one long, meta-narrative SONG, which was sung in melody on in and every relevant occasion. In this way, the songs and visual elements of the Bible have permeated the symbolic imagery and spiritual expressions of the Church. Since we receive our symbolism and imagery from the same fount, it is reasonable to find many similarities, some by design and some by sheer coincidence.
Was there anything more specific you had in mind to discuss regarding the Jewish liturgy?
