I don’t understand what is the big deal if Jesus had a wife or not it. He is a Jewish man. Jewish men get married. I don’t see how any of that would change His life or Him being the Redeemer.
Since Jesus said his Father must be worshiped ‘in spirit and truth’ then it would follow knowing the truth of the matter is of importance. A married Jesus with the possibility of a family is a different Jesus than one who had no place to lay down his head and no attachments to this world.
Further, celibacy is an important aspect of Christianity. Consider:
If any man come to me, and hate not his father, and mother, and wife, and children, and brethren, and sisters, yea and his own life also, he cannot be my disciple ... likewise every one of you that doth not renounce all that he possesseth, cannot be my disciple. (Luke 14:26,33)It would be inconsistent if the Author of the speech written down by st. Luke, and the teacher of St. Paul who was celibate by conviction and advised celibacy to others, be Himself married.
...For I would that all men were even as myself: but every one hath his proper gift from God; one after this manner, and another after that.  But I say to the unmarried, and to the widows: It is good for them if they so continue, even as I.  But if they do not contain themselves, let them marry. (1 Cor.7:7-9)
