It is no more silly than teaching the earth is 6000 years old, that God has a magic tractor beam to whiff those who said the magic word off to avoid the Antichrist and his minions, that it was meet and right for the alleged "pure" Israelites to massacre their "impure" neighbors and former cousins over a piece of land not worth having in the first place, that a man lived in the giant belly of a huge fish for three days and nights, or that a talking snake sweet talked a chick and she convinced her husband and herself to eat a piece of fruit and so the golden age was ended.
What is not silly: The Beatitudes, the Lord's Prayer, the example of Our Lord in turning the other cheek and yielding not to temptation -- being faithful even unto death, publicly confessing one's faith, one's belief in the birth of God's Son by the Blessed Virgin Mary and becoming flesh, bore our sins for us, teaching us the way of Heaven's Desire, and rising into Heaven after resurrecting from the dead after two evenings buried and then coming in the future at an unknown date to judge the living and the dead and whose kingdom shall have no end, as it exist now in our faith and shall be perfected in Paridise. That is not silly, that is the orthodox faith and no amount of ancient Proto-Hebrew superstition, tribal taboo or uninformed pseudoscience can undo it.
You can take all the crazed frentic holy rollers and tribulators, rapturators, and snake handlers and they as a group lack the simple common faith of an illiterate peasant from the Middele Ages. Not content with being just one out of many, these people, alleged clergy and preachers and theologians add and subtract from the Gospel as it suits them, calling it God's Word as recently revealed in fullness and truth, making themselves bigger fishes in a smaller group of ponds and frequently enriching not only their egos but their pocketbooks as well.
