We as believers must place a great priority upon the centrality of God’s Word among his people. By gathering together for the public reading of Scripture—from the very beginning of the service—it places a priority upon the Word. An honest evaluation for all believers would be to compare the amount of singing to the amount of God’s Word in a typical weekly worship service. Which one takes the priority?
Years ago, I was forced to attend a Roman Catholic Church mass to fulfill a requirement for a class I was taking in seminary. At first, I was not too pleased with this assignment, but as it turned out, it was quite an eye-opening experience to be sure. For me, having grown up as a protestant, I had never attended a Roman Catholic worship service—and I certainly had been taught much of their errors through the years. While I refused to engage in the mass due to the heretical teaching of transubstantiation, I left convicted. As a pastor of a local church and a seminary student, I was convicted for the lack of public reading of Scripture in our protestant worship services.
Over the years that would follow, I would eventually lead our church to incorporate more rather than less Scripture in worship. Why is the public reading of Scripture important and essential for our worship of God?
1 Timothy 4:13 — Until I come, devote yourself to the public reading of Scripture, to exhortation, to teaching.
Establishing the Priority of Scripture for Worship
At the center of every Christian worship service must be the Word of God. We as believers must place a great priority upon the centrality of God’s Word among his people. By gathering together for the public reading of Scripture—from the very beginning of the service—it places a priority upon the Word. An honest evaluation for all believers would be to compare the amount of singing to the amount of God’s Word in a typical weekly worship service. Which one takes the priority?
As Paul wrote to Timothy (1 Tim. 4:13), he pointed him to the public reading of Scripture. Since books were scarce (especially parchments of God’s Word) and the educational level of people during the days of the early church often lacked the ability to read—the only time people could hear the Word of God was during public worship. Justin Martyr described a worship service from the second century:
On the day called Sunday, all who live in cities or in the country gather together to one place, and the memoirs of the apostles or the writings of the prophets are read, as long as time permits; then, when the reader has ceased, the president verbally instructs, and exhorts to the imitation of these good things. 
Each week as we gather for worship within the context of the church that I serve, we have an official call to worship from God’s Word. This is a means of the church being called to worship God through his Word from the beginning of the service. Such an official call to worship sets the stage for the fact that all of our worship must be connected to God’s Word, driven by God’s Word, directed by God’s Word, and honoring to the God of the Bible. We likewise desire to communicate to everyone who is present that the Word of God takes priority over everything else in our service.
