Scripture failing to mention that something happened doesn't give people license to make stuff up, claim it happened, and pass it off as Truth, simply because because *it could have happened.*
Sure, but Scripture failing to mention something doesn't mean that it didn't happen, either. Scripture isn't a complete history, and our understanding of Christ was passed down to us both through written and oral traditions and practices.
As well as...
Scripture failing to mention that something will be found in a cave under a hill in a yet undiscovered continent, that will correct (uh, restore) the ERROR found in existing scripture.
However, that will NOT 'correct' enough, so one man will receive 'messages' from GOD that adds to the first correcting message.
Oh, yeah. that won't be enough so messages hidden in ancient Egyptian papyri will be found to contain even more information that was purposefully removed from the early days of Christianity.
