Syriac is close to the language of Christ. In particular, the Peshitta (a translation of the New Testament in Aramaic) is written in the ancient Estrangela form of Syriac. Later Christian writings were also written in Western and Eastern versions of Syriac and prove vital for Theological studies -particularly in the area of textual criticism.
By studying Syriac, you will almost feel as though you can hear the words falling from the lips of Christ and begin to understand not only the language but the culture and mindset of a Galilean such as Messiah with his their simple parabolic style of speaking and story-telling.
