Christian according to the 2007 Pew Religious Landscape survey. Out of all Americans who identify as unaffiliated including atheists and agnostics, 41% were raised Protestant and 28% were raised Catholic according to the 2014 Pew Religious Landscape survey. Protestantism In the Netherlands, 42% of the members of the Protestant Church in the Netherlands (PKN) are nontheists. Non-belief among clergymen is not always perceived as a problem. Some follow the tradition of "Christian non-realism", most famously expounded in the United Kingdom by Don Cupitt in the 1980s, which holds that God is a symbol or metaphor and that religious language is not matched by a transcendent reality. According to an investigation of 860 pastors in seven Dutch Protestant denominations, 1 in 6 clergy are either agnostic or atheist. In one of those denominations, the Remonstrant Brotherhood, the number of doubters was 42 percent. A minister of the PKN, Klaas Hendrikse has described God as "a word for experience, or human experience" and said that Jesus may have never existed. Hendrikse gained attention with his book published in November 2007 in which he said that it was not necessary to believe in God's existence in order to believe in God.

Hendrikse writes in the book that "God is for me not a being but a word for what can happen between people. Someone says to you, for example, 'I will not abandon you', and then makes those words come true. It would be perfectly alright to call that [relationship] God". A General Synod found Hendrikse's views were widely shared among both clergy and church members. The February 3, 2010 decision to allow Hendrikse to continue working as a pastor followed the advice of a regional supervisory panel that the statements by Hendrikse "are not of sufficient weight to damage the foundations of the Church. The ideas of Hendrikse are theologically not new, and are in keeping with the liberal tradition that is an integral part of our church", the special panel concluded. A Harris Interactive survey from 2003 found that 90% of self-identified Protestants in the United States believe in God and about 4% of American Protestants believe there is no God. In 2017, the WIN-Gallup International Association (WIN/GIA) poll found that Sweden, a majority Christian country, had second highest percentage
