Some may ask why it is so important to know the exact day Jesus was crucified. There are several reasons with the most important being to make certain that the accuracy of the Biblical prophecy is maintained. If even 1 of the prophecies about the Messiah had not be consistent, that is enough to disqualify Jesus from even being considered as a possible candidate for Messiah. The next reason to maintain the authority of our Creator when conveying the message to others. Who would believe and trust a Creator who is not absolutely consistent? Remember Eve failed to maintain the sacred word of our Creator and the serpent was able to trick her, we should be careful to guard His word and not rely on fallible traditions. The stakes are too high as we live to be His representatives on earth.
