Originally published in 1648 under the elaborate title "Eshcol: A Cluster of the fruit of Canaan; brought to the Borders, for the encouragement of the Saints, travelling thitherward, with their faces towards Zion. OR. Rules of direction, for the walking of the Saints in Fellowship, according to the order of the Gospel," this work remains a seminal text in understanding the essence of healthy church fellowship and membership.

In "Duties of Christian Fellowship," John Owen provides an insightful exploration into the essence of congregational life and mutual responsibilities within the Christian community. His work, deeply anchored in scriptural teachings, offers a comprehensive guide to ecclesiastical fellowship and discipline.

The book is meticulously structured into two main sections. The first outlines the duties of church members towards their pastor, encapsulating seven distinct rules that emphasize respect, support, and adherence to pastoral leadership based on biblical foundations. The second section expands on the responsibilities of church members towards one another, detailing fifteen rules that promote unity, mutual care, and spiritual edification within the body of Christ.

Owen's writing is not only a testament to his profound understanding of scripture but also reflects his deep piety and sound judgment. His work transcends denominational lines, offering timeless wisdom applicable to any ecclesiastical polity. "Duties of Christian Fellowship" stands as a manual on church fellowship that continues to guide and inspire believers in their communal Christian walk.
