Christianity grew out of Judaism.
The first Christians were Jews who still practised their Judaism as well as accepting Jesus as Messiah, so that in the early days of the Christian Church it was regarded as a Jewish sect rather than a religion in its own right.
However, as more and more non-Jews were converted, thanks to the evangelism of the apostles (especially Paul) across the Roman Empire, the new religion gradually split from Judaism, and its customs (such as the insistence of male circumcision and the ban on eatng pork) were dropped.
Judaism and Christianity
Christianity shares its early history with Judaism, as Jesus and his followers were Jewish. Additionally, Christianity also shared some early history with Greco-Roman religions, as it spread throughout the Roman Empire and interacted with pagan practices and beliefs.
They are all considered 'different' to other religions (eg. Christianity or buddismn), or they aren't 'book religions'
they are all Monotheistic Religions.
The major element that sets Christianity apart from other religions is the belief in Jesus Christ as the Son of God and the savior of humanity. This central tenet of Christianity distinguishes it from other faiths that do not share this belief in Jesus as the divine figure who offers salvation to believers.
