No, I have no Jewish lineage. Truth be told, calling myself a Messianic Jew is a bit misleading, but in a multiple choice list, it is the closest to my personal beliefs because it is, what I believe, to be the closest to Christianity as Jesus meant it. The Protestant churches today (I am not an expert on any other kinds) have a tendency to separate Judaism from Christianity which I do not believe was Jesus' intention. That's why I claim to be a Messianic Jew rather than any sort of protestant, Catholic, or orthodoxy.
