Hausherr has shown himself both in this work and in his earlier, closely related book Penthos,
to be one wholly concerned with the most intimate aspects of Christian spirituality. What he has accomplished is not merely an investigation of the ways Christians have addressed Jesus from New Testament times down through the first millennium, nor simply a history of the Jesus Prayer. This book contains a relentless quest for the underlying orientation of Christian people toward their Lord. With a rare familiarity with countless Eastern and especially Syriac liturgical and monastic texts, Hausherr reveals the close connection between compunction, or sorrow for sin, and the desire to find methods of unceasing prayer. In the course of his investigation, he has much of importance to say about the essence of prayer, authentic piety, and authentic holiness. 358 pp.
An Eighth Day View:
"Pray continually," Scripture exhorts. "Do everything in the name of the Lord Jesus." Striving to obey, christian monks of the East joined adoration and compunction in unceasing prayer. In the course of fourteen centuries, they developed what some have called 'the only perfect way of prayer, ' the Jesus Prayer: Jesus Christ, Son of God, have mercy on me (a sinner).
