What is relegation of religion to the private sphere of life

The relegation of religion to the private sphere of life means that religious belief and practice are considered a personal and individual matter, primarily confined to one's home, family, and private conscience. In this view, religion should not play a direct role in public policy, government decisions, education, or other secular institutions. It implies a separation where religious values and expressions are largely excluded from the public square, with public life governed by secular principles accessible to all, regardless of their faith.
