Apparently not. You said the hint was "heavenly father", so I looked that up. The article mentions Judaism, Christianity, Eastern Orthodoxy, Jehovah's Witnesses, Oneness Pentecostalism, Mormonism, Islam, Other religions, Hinduism and Confucianism.

That's irrelevant. In the United States, both "heavenly father" and "amen" are Christian themes.
