You have just stated the very pillar of liberalism!!
Jesus could NOT have been married and still be who He is. The Old Testament prophesies concerning Him would all be invalidated.
This is nothing more than an agenda feeding on people's ignorance of the Scriptures.
Precisely!
If Jesus was not a sinless man, truly born of a virgin which would be the only way to start out sinless and remain sinless until death, the He was not the "spotless Lamb of God" our atoning sacrifice.
If Jesus was not the "way, the truth and the life" or better translated into modern speech; "I Am the way, the true way, the way to eternal life. No one comes to the Father but by me".
If Jesus is not the only begotten Son of God, then we are basically screwed and have no hope or prayer in this world...or the next.
I Plead ignorance on this point. Please cite the scripture you have in mind.
