Here's where the application of some simple logic can work wonders. Would the Bible, with its emphasis on the sanctity of marriage and the importance of family, have omitted something as significant as the marriage of Jesus in capturing the great events of His life?
And would the Jewish betrothal customs (so predictive of the Second Coming where our Lord takes the Church as His Bride) which required a public commitment ceremony followed by a year of very limited and closely chaperoned visitation have been ignored and in fact violated by the One Who ordained them?
And how about this? Jesus came to be our High Priest. The Law forbids a priest from marrying a woman who isn't a virgin unless she's the widow of another priest. The High Priest couldn't marry a non-priestly widow and was specifically forbidden from marrying a prostitute. (Lev 21:13-14) Jesus said He didn't come to abolish the Law but to fulfill it.
In Genesis 6 the Bible says that one reason for the Great Flood was to judge those from the angelic host who took on the appearance of men, married human women and produced children contaminating the human gene pool. Would a Righteous and Just God now take this privilege for Himself while holding those others in chains for judgment? Think about it!
But most importantly would God, who became man to offer His sinless life as a ransom for the sins of humanity, have permitted His mission to be destroyed and mankind to be lost by falling into sin Himself? The reason for the restrictive betrothal customs was to keep the couple from yielding to temptation. Remember any sex outside of marriage was punishable by death in those days, and the Lord himself cautioned us that even lustful thoughts render us guilty (Matt 5:28). His own Law required the shedding of innocent blood as the only acceptable sacrifice for sin. In order to be our Savior, He had to remain sinless in thought, word, and deed.
Proponents of this theory are trying to portray Jesus as a mere man. Could a man, in love with a beautiful woman, prevent even one lustful thought from entering his mind? And if his betrothed was a former prostitute could he prevent anger and jealousy from ever raising their ugly heads as well? It doesn't make sense!
Clearly this notion of a relationship between Mary and Jesus violates both the letter and the spirit of the Law. It's the work of unbelievers who are themselves ignorant of Biblical truth and rely on the ignorance of others for their acceptance.
And behind the scene just beyond the limit of our vision stands the Great Deceiver preying on those ignorant souls, using them to distort and pervert the Word of God in his frantic attempt to render humanity hopeless and helpless, portraying our only Savior as having disqualified Himself to redeem us.
These attempts will become more and more persuasive as the time draws closer. Let this serve as a warning, that we must know what we believe and why to withstand these attacks on our faith.
