Robert Owen was openly critical of certain aspects of Christianity and made many enemies in this respect. In 1823 he suggested to his school teachers that the pupils would learn more from geography than the Bible. He deemed the Scottish Sabbath a day of 'superstitious gloom and tyranny over the mind', and 'the most destructive intemperance and licentiousness.'
He was otherwise tolerant towards religious practices. He encouraged church going, which he believed promoted responsibility and good behaviour.
Owen's secularism and socialism provoked suspicion among conservative thinkers.
