Francis Chege Keiru in this book entitled “Ecclesiastical Pillars often lgnored Today" is a well-researched book reflects upon the book of John 17:1-26. The prayer of Jesus for all the believers of the world bringing about the unity aligned with the purpose of God. The writer brings the idea of ecumenism which is paralleled in a similar manner where Paul in the scripture talks about the Church as a body with many parts that synchronize together for the benefit of the whole body (1 Corinthians 12: 12-27). We are one body in Christ and we all joined together to each other but different parts of the same body. The call for the ecclesiastical body has one mandate from Christ, the owner of the universal church: to preach Christ and to make Him known to all nations of the world in order to reconcile all people to God through the saving grace of Jesus Christ. The book is theologically oriented and it is a resourceful book which is a must-read by all churches such as African Initiated Churches Pentecostals, Evangelicals, Mainstream churches as well as those in theological institutions. May God use this book to encourage many who find themselves separated from the unity aligned to the purpose of God in Jesus Christ.
