Would you question the “authenticity” of a document whose major premise was: the cow jumped over the moon?
Is it reasonable to question the legitimacy of a document whose major premise is: God really, really loves you, and if you don’t believe it, He will allow/arrange for you to burn in hell forever?
Both of the premises are ridiculous.
You are making commentary on something you have no idea (your claim, no?) is authentic or not? Or are you conceding the scriptures are true but you reject the message?
My point is how can you argue against authenticity based on a conceived concept that such scriptures tell us God is "unfair." Your reasoning seems to be "since I think God is unfair in His judgments, therefore the message and messengers must be false or in error."
One might say we would be using a "crutch" of thinking the scriptures may be in error or false in order to argue there is no such judgment (as mentioned in scriptures).
I would if hundreds and thousands of witnesses saw the cow jump over the moon. God in the OT did many things for many to witness. Jesus Christ did all of His miracles in front of hundreds and sometimes thousands. After His resurrection, Paul tells us this:
1 Corinthians 15:
3 For I delivered to you as of first importance what I also received, that Christ died for our sins according to the Scriptures, 4 and that He was buried, and that He was raised on the third day according to the Scriptures, 5 and that He appeared to Cephas, then to the twelve. 6 After that He appeared to more than five hundred brethren at one time, most of whom remain until now, but some have fallen asleep; 7 then He appeared to James, then to all the apostles; 8 and last of all, as to one untimely born, He appeared to me also. 9 For I am the least of the apostles, and not fit to be called an apostle, because I persecuted the church of God. 10 But by the grace of God I am what I am, and His grace toward me did not prove vain; but I labored even more than all of them, yet not I, but the grace of God with me. 11 Whether then it was I or they, so we preach and so you believed.
dang!
Them dumb JEWS should have seen this problem arising, and adjusted their Scriptures accordingly!
