“GRACE is an affiliation of Civil and Foreign Service professionals working to promote a culture at the State Department that embraces the ability of employees to manifest religious belief generally, and Christianity specifically, in the workplace. GRACE seeks to connect Department employees that share this vision; to advocate for religious freedom and religious expression for everyone within the Department; and to highlight the value added by the perspective of people of faith in general, and Christians in particular, to the Department and its mission. In doing so, GRACE aspires to emulate Jesus’ love and respect for all people, regardless of their background or religion. Accordingly, GRACE’s membership is open to all Department employees and contractors, whether stateside or deployed overseas. For more information, please contact GRACE@state.gov.”
