That depends on the type of event that's going on.
There is no prohibition against bringing non-Jews to an Orthodox synagogue or otherwise, it happens all the time.
In the time of Jesus in Israel the religious houses were called synagogues, and yes Jesus preached in these. In Luke 4:16-30 is the story of Jesus going to the town he was raised in and preaching in that synagogue.
The institution of the synagogue appears to have originated between the time of the Babylonian exile an the time of Jesus. There were no synagogues before the exile, and there were lots of them by the time of Jesus. Nobody knows who built the first one, nor do we know whether it was built in Babylon before the return from exile or in Judea and Galilee after the return. It is almost certain that the first synagogue was organized using an existing building, and that the institution of the synagogue was around for a while before the first purpose-built synagogue was built.
It is different every year. You will need to call a synagogue or check a Jewish calendar website.
The synagogue that Jesus regularly taught in was made of black basalt stone and archaeologists date it back to at least 1AD today the only main wall left in the synagogue is the wailing wall. the women and children where not allowed past certain parts of the synagogue and had to worship in a place called the women's court. the outside of the synagogue was just a plane grey stone. the grandest part of the synagogue is the sacrifice chamber only Jewish men and priests were allowed in the synagogue.
The Jewish house of worship is called synagogue, although Jews can worship G-d anywhere at any time.
Yes, but most only wear it inside the synagogue or at home during Jewish prayers. Some wear it all the time, just like the Orthodox.
Yes, non-Jews attend Orthodox synagogue services all the time, usually as an invited guest to an event. If you wish to attend a religious service at an Orthodox synagogue, you might want to contact the synagogue's rabbi first to determine the best time to attend. As for being circumcised or not, it doesn't make a difference as male circumcision is only a concern for Jewish males. As non-Jewish person can't participate in a Jewish religious service anyway, being uncircumcised is a moot point.
Hebrews today are called Jews. A Jewish house of worship is called a synagogue or temple, but Jews can worship anywhere they want, at any time.
The time for Shabbat varies each week and depends on your location. To find the exact time for Shabbat this week, you can check a Jewish calendar, a local synagogue's website, or use a Jewish time calculator specific to your area. Shabbat typically begins at sunset on Friday and ends at nightfall on Saturday.
Since a public school system did not exist at the time Paul would have been a child, he probably received most of his education at the local Jewish Synagogue.
He was Jewish, and one time a world series game fell out on Yom Kippur (the Jewish Day of Atonement), and he sacrificed a WORLD SERIES GAME just to go synagogue on Yom Kippur.That is what I call special.Do you think so?
