Greek Orthodox and Syrian Orthodox are two separate branches of the Eastern Orthodox Church. The Greek Orthodox Church is one of the oldest Christian denominations, tracing its roots back to the early Christian communities in Greece. The Syrian Orthodox Church, also known as the Syriac Orthodox Church, has its origins in the ancient Christian communities of the Middle East, particularly in Syria and the surrounding regions. Both churches have their own distinct traditions, liturgies, and hierarchies, but they share the same core beliefs and are part of the larger Eastern Orthodox communion. **

The difference between orthodox and ultra-orthodox lies in the level of adherence to traditional religious practices and beliefs within Judaism. Orthodox Jews generally adhere to traditional Jewish law and customs, but may also engage with modern society to varying degrees. Ultra-orthodox Jews, on the other hand, tend to strictly adhere to traditional religious practices and often live in more insular communities, with limited engagement with secular society. Ultra-orthodox Jews also typically place a strong emphasis on Torah study and religious observance. **

It is complicated to distinguish between Orthodox Bosnians and Orthodox Serbs from Serbia because they share the same religious denomination, Orthodox Christianity. Additionally, they may also share similar cultural and linguistic traits, making it difficult to differentiate between the two groups based solely on religious or cultural markers. Furthermore, the complex history of the region, including periods of coexistence and conflict, has led to intermingling and intermarriage between the two groups, further blurring the lines of distinction. As a result, it can be challenging to accurately identify individuals as either Orthodox Bosnians or Orthodox Serbs from Serbia based on external characteristics alone. **

Yes, it is allowed for a Russian Orthodox believer to attend another Orthodox church. The Orthodox Church is a communion of autocephalous (self-governing) churches, and they share the same faith and sacraments. Therefore, a Russian Orthodox believer can participate in the services and receive the sacraments in another Orthodox church, such as Greek Orthodox or Serbian Orthodox, as long as they are in good standing with their own church and follow the guidelines of the church they are visiting. It is important to respect the traditions and practices of the church being visited while maintaining one's own faith and traditions. **

Professing the Greek Orthodox creed alone does not automatically make someone Greek Orthodox. Becoming Greek Orthodox typically involves a process of instruction, baptism, and chrismation, as well as a commitment to the teachings and practices of the Greek Orthodox Church. Professing the creed is an important part of this process, but it is not the sole factor in becoming Greek Orthodox. **

Circumcision is more commonly associated with certain other religious and cultural traditions, such as Judaism and Islam. **
