When Modern Church began at the end of the nineteenth century the founding members called it a society 'for the advancement of liberal religious thought'.
At the time many educated people thought science had disproved the existence of God, or soon would. Many Christians reacted by rejecting modern science, and produced a movement later called 'fundamentalism'.
'Liberal religious thought' meant refusing to accept the opposition between science and religion. They were prepared to adapt their religious beliefs in the light of new evidence - about, for example, evolution and the historical accuracy of the Bible. Yet they remained confident that science would be a companion, not an opponent, to religious belief.
