doctrine (that is, those who remained, since a significant majority of the church's original membership left), and in 2008, the congregation was merged into All Souls Unitarian Church in Tulsa, Oklahoma, one of the largest Unitarian Universalist congregations in the world. The Evangelical Universalist: The Biblical Hope That God's Love Will Save us All, by "Gregory MacDonald", was published in 2006. "Gregory MacDonald" is a pen name, and the book's author was later revealed to be Robin Parry. The same author is also a coeditor of a 2003 compilation, Universal Salvation? The Current Debate, and of a 2010 book, All Shall Be Well, which reviews the doctrine of universal salvation from Origen to Moltmann. On May 17, 2007, the Christian Universalist Association was founded at the historic Universalist National Memorial Church in Washington, DC. That was a move to distinguish the modern Christian Universalist movement from Unitarian Universalism and to promote ecumenical unity among Christian believers in universal reconciliation. In 2008, the Russian Orthodox scholar-bishop Hilarion Alfeyev of Volokolamsk, in his presentation at the First World Apostolic Congress of Divine Mercy (held in Rome in 2008), argued that God's mercy is so great that He does not condemn sinners to everlasting punishment. He said that the Orthodox understanding of Hell corresponds roughly to the Roman Catholic notion of purgatory. American Eastern Orthodox theologian David Bentley Hart has also argued for the coherence of the universalist position, most notably in That All Shall Be Saved: Heaven, Hell, and Universal Salvation (2019). In her massive 2013 monograph The Christian Doctrine of Apokatastasis, A Critical Assessment from the New Testament to Eriugena, Ilaria L.E. Ramelli argues that apokatastasis (restoration) is a major patristic doctrine stemming from Greek philosophy and Jewish-Christian Scriptures. She makes the case for its presence and Christological and Biblical foundation in many Fathers, analysing its meaning and development from the birth of Christianity to Eriugena. Contemporary Conservative Evangelical teachers of ultimate reconciliation include Thomas Talbott and J.D. Leavitt, founder of Heavenly Faith. Two Christian theologians of the 20th and 21st centuries who wrote in support of universalism and have received major notice are also J.A.T. Robinson and John Hick. Both argued for universalism as coming from God's nature as being of omnipotent love and stated that as time went on after death, some would temporarily refuse to repent, but none would refuse to repent forever. Hick, in particular, stated that
