The Internet School of Orthodox Studies Fall 2003 program is designed to help Orthodox Christians understand the Orthodox faith. This series is presented by Rev. Dr. Frank Marangos and Rev. Dr. George Bithos.
Established by the Department of Religious Education in 1998, ISOS ran through the Fall of 2005 as a means to assist Orthodox Christians to better understand the teachings of the Orthodox Church. These classes have been archived on the goarch.org website with the assistance of the Archdiocese Department of Internet Ministries.
