Historical Context
Stephen's life unfolded during the first period of Byzantine iconoclasm, the imperial policy — advanced sharply under Constantine V — of suppressing the making and veneration of religious images. The iconoclast Council of Hieria in 754 gave the policy a conciliar endorsement, and monastic communities, which were strongholds of icon veneration, bore much of the ensuing persecution.
As an abbot whose monastery was known for its ascetic rigor and adherence to the veneration of icons, Stephen became a conspicuous and influential opponent of the imperial program. The emperor is reported to have regarded him as a strong and implacable adversary, and efforts were made to break his resistance first by inducement and then by coercion and slander.
