Hughes Oliphant Old was a significant scholar of the history of Christian worship.
His death means that what he knew in part, he know experiences in power.
Christian worship is in the name of Christ because worship is a function of the body of Christ and as Christians we are all one body. All of our worship must be in him! What an important New Testament concept this is that the church is the body of Christ, and how vividly the first Christians understood that they were all together one body, the body of Christ. They understood their worship to be part of the worship that the ascended Christ performed in the heavenly sanctuary to the glory of the Father (Heb. 7:23-25; 9:25; 10:19-22; 13:15).
If reformed theology is concerned that worship be according to God’s Word and in obedience to God’s Word and if Reformed theology has made a point of worship being in the name of Christ and in the body of Christ, it is most surely because of us realised that worship is far more than a human work. Worship is the work of the Holy Spirit.
