If that were true, then it would be a second AND a third coming, not two second comings. For the life of me, I’ve never been able to find any apostle or early christian ever talking about a third coming.
Thats what the ancient Jews thought and thats why they missed their messiah. They thought He was coming only once. They did not understand He was coming as the suffering servant before His return as the conquering King.
A second and a third coming? that's false.
