(RNS)  -- The oft-cliched Christian notion of heaven -- a blissful realm of harp-strumming angels -- has remained a fixture of the faith for centuries. Even as arguments will go on as to who will or won't be "saved," surveys show that a vast majority Americans believe that after death their souls will ascend to some kind of celestial resting place.

But scholars on the right and left increasingly say that comforting belief in an afterlife has no basis in the Bible and would have sounded bizarre to Jesus and his early followers. Like modern curators patiently restoring an ancient fresco, scholars have plumbed the New Testament's Jewish roots to challenge the pervasive cultural belief in an otherworldly paradise.

The most recent expert to add his voice to this chorus is the prolific Christian apologist N.T. Wright, a former Anglican bishop who now teaches about early Christianity and New Testament at Scotland's University of St. Andrews. Wright has explored Christian misconceptions about heaven in previous books, but now devotes an entire volume, How God Became King: The Forgotten Story of the Gospels, to this trendy subject.

Wright's insistence that Christianity has got it all wrong seems to mark a turning point for the serious rethinking of heaven. He's not just another academic iconoclast bent on debunking Christian myths. Wright takes his creeds very seriously and has even written an 800-plus-page megaton study setting out to prove the historical truth of the resurrection of Jesus.

"This is a very current issue -- that what the church, or what the majority conventional view of heaven is, is very different from what we find in these biblical testimonies," said Christopher Morse of Union Theological Seminary in New York. "The end times are not the end of the world -- they are the beginning of the real world -- in biblical understanding."

Still, the appearance of a recent cover story in Time magazine suggests that putting-the-heaven-myth-to-rest movement is gaining currency beyond the academy. Wright and Morse say they have both made presentations on heaven research at local churches and have been surprised by the public interest and acceptance.

"An awful lot of ordinary church-going Christians are simply millions of miles away from understanding any of this," Wright said.

Wright and Morse work independently of each other and in very different ideological settings, but their work shows a remarkable convergence on key points. In classic Judaism and first-century Christianity, believers expected this world would be transformed into God's Kingdom -- a restored Eden where redeemed human beings would be liberated from death, illness, sin and other corruptions.

"This represents an instance of two top scholars who have apparently grown tired of talk of heaven on the part of Christians that is neither consistent with the New Testament nor theologically coherent," said Trevor Eppehimer of Hood Theological Seminary in North Carolina. "The majority of Christian theologians today would recognize that Wright and Morse's views on heaven represent, for the most part, the basic New Testament perspective on heaven."

First-century Jews who believed Jesus was Messiah also believed he inaugurated the Kingdom of God and were convinced the world would be transformed in their own lifetimes, Wright said. This inauguration, however, was far from complete and required the active participation of God's people practicing social justice, nonviolence and forgiveness to become fulfilled.

Once the Kingdom is complete, he said, the bodily resurrection will follow with a fully restored creation here on earth. "What we are doing at the moment is building for the Kingdom," Wright explained.
