In order for this to occur, he would have discovered the true Golgatha location that is disputed for centuries. That first would have been very newsworthy. The Ark of the Covenant will never be found or displayed in my opinion. The Spirit of God no longer resides in it and dwells in the hearts of men and women who accepted Jesus as Savior - Our promised Comforter. To find the Ark would serve no purpose to man. A better covenant ensued for all who will receive.
