The term "Plain Christians" isn't a specific biblical phrase found in Scripture; rather, it is often used in contemporary discussions to describe Christians who adhere to a straightforward, uncomplicated faith in Jesus Christ, emphasizing the essentials of the Gospel without the encumbrances of complex theological debates or denominational divisions. This concept resonates with the biblical call for believers to have childlike faith (Matthew 18:3) and to focus on the core tenets of Christianity, such as love for God and neighbor (Matthew 22:37-40) and the proclamation of Jesus as Lord and Savior (Romans 10:9).In a broader sense, the idea can be linked to the early church's simplicity. Acts 2:42 describes the early Christians as devoted to the apostles' teaching, fellowship, breaking of bread, and prayer—elements that reflect a plain yet profound commitment to their faith. In this context, being a "Plain Christian" might also imply living out one's faith authentically and practically, emphasizing moral integrity and a genuine love for others, as seen in James 1:27, which calls for pure religion to be caring for orphans and widows in their distress. Thus, while "Plain Christians" may not be a biblical term, it embodies a spirit of simplicity and sincerity that aligns well with biblical teachings.
