@ Scholar.
Thank you for clarity.
My take is that all three dates are based on eisegesis and that Jehovah's Witnesses would not baptize anyone who does not tow the line completely. Why baptize someone who you would later disfellowship for expressing disagreement on any officially marked dates or doctrines?
Without 1914 Jesus Christ's invisible presence and enthronment remain undetermined and undeterminable.
Without 1918 all the churches are still approved temples of God as they were before 1918. So the religion of Jehovah's Witnesses no longe can claim the status of being the one true religion.
Without 1919 the men taking the lead in Warwick are not the Faithful Slave they are claiming to be and therefore do not have God-given authority and mandate to channel God's truth to mankind and then, of course, the entire house of cards collapses.
So, my take is that to be baptized as a Jehovah’s Witness all three extra-biblical dates and the invisible events associated with them would have to be believed.
Now none of these dates were criteria for Christian baptism before the twentieth century...so why is believing in these dates so critical now if one can be a true Christian while rejecting all three?
And if one is a true Christian without faith in 1914, 1918 and 1919, then it is not only Jehovah's Witnesses that have a scriptural hope of surviving Armageddon after all.
