Christianity has no religious idea that lacks resemblance to surrounding religions. Religions do not need to copy each other to have similar ideas, the reason is that the way in which humans deal with divinity is limited. We can say that Christianity has some aspects that are not present in Judaism, the contemporary religion. For example, the virginity of Mary. In Judaism there is no eulogy of virginity. However, there are priestesses in the Greek world who could be sentenced to death if they were caught in some sexual sin. Virginity is therefore a Greek good, not a Semitic good. The institution of the Eucharist through which the bread and wine become the body and blood of Christ is not understood in the Jewish sphere either. For Judaism the existence of the Holy Trinity is also impossible, however, we see these ideas in Platonic philosophy.
