"America embraces people of all faiths and of no faith. We are Christians and Jews, Muslims and Hindus, Buddhists and Sikhs, atheists and agnostics," Obama said in a proclamation to declare January 16 as the Religious Freedom Day.
"Our religious diversity enriches our cultural fabric and reminds us that what binds us as one is not the tenets of our faiths, the colours of our skin, or the origins of our names.
"What makes us American is our adherence to shared ideals -- freedom, equality, justice, and our right as a people to set our own course," he said.
"In the years to come, my Administration will remain committed to promoting religious freedom, both at home and across the globe," Obama said.
He also urged every country to recognise religious freedom as both a universal right and a key to a stable, prosperous, and peaceful future.
