"Part of the context of this question is that it is written that Jesus was called "Rabbi", yet Christian canon holds that Jesus was never married (a claim of which I am skeptical)."
In response to this part of your inquiry, I can answer you that, by the time of Jesus, the title "rabbi" and correlates were not exclusively used in a formal manner as it is today in judaism in reference to authorized clergy. On the contrary, it was sometimes used in reference to non-clergy and non-pharisaic individuals who had acquired a religious following as a means of attributing honor. Also, not all recognized pharisaic authorities (that time's rabbis) had the rabbi title attached to their names, as was, for example, the case for Hillel The Elder. Later rabbinc authorities also don't always have the title, as is the case for the Sage Shmuel, and many others.
All this to say that: even if it could be proven that in rabbinic judaism historically one would have to be married to be a recognized rabbi, it does not follow from it that Jesus was married just because he was called a rabbi, since the title was not exclusively used in this formal manner by that time, being some times attributed to religious leaderships independent of formal training, recognition and, needless to say, any other requirement for official ordination as a rabbi.
