Christina McGuire was raised Catholic by her father and Lutheran by her mother. She attended Catholic school as a child but became more open-minded about religion after moving to different countries. While she was confirmed in the Catholic church, she stopped regularly attending services as a teenager and now identifies as agnostic, believing in a higher power but not a specific religion. Her experiences living in diverse places and being influenced by family and friends have led her to adopt a spiritual but not strictly religious viewpoint.
