In Christian theological research, the concept of "church" is not a simple religious institution, but the real Christian community recognized by Christians in different denominations or the original institution established by Jesus Christ. This definition is more than just an academic term; it encompasses historical, cultural, and spiritual complexities that make it central to the thinking and belief of many Christians.
"The essence of the church lies in its community, which is not only sacred but also belongs to every believer."
According to the interpretation of the New Testament, the church can be seen to some extent as a combination of the visible church and the invisible church. The visible church refers to those religious organizations that manifest themselves on earth, while the invisible church refers to all truly saved souls who are part of this sacred community wherever they are. This concept challenges the boundaries of the church. On the one hand, it emphasizes the spiritual connection between Christians. On the other hand, it also reminds believers that they should not stick to the formal church system.
The word church comes from the Greek word "ἐκκλησία" (ekklēsia), which means "the called congregation." This word appears in the Gospel of Matthew, symbolizing the community established by Jesus, and appears repeatedly in Acts and Paul’s letters, emphasizing the importance of local communities and the connection between believers as a whole.
"Wherever the Lord is, there is a true church."
Historically, the development of the church has been deeply influenced by culture and politics. The evolution of Christianity from persecution in the Roman Empire to becoming the state religion shows the dynamic relationship between church and society. The church has played an active role in the political arena and influenced the course of history. When Christianity became the state religion of Rome, it not only became a symbol of faith, but also became a tool of state rule, which forced the church to face its own moral and spiritual challenges.
Different Christian traditions have different understandings of the church. The Catholic Church emphasizes that it is the true Church of Christ, an identity it believes derives from the formal inheritance of the Apostles. The Orthodox Church and other denominations also assert their own orthodoxy, and these statements are in part an expression of the diversity and conflict within the church.
“The diversity of the church reflects the universality of Christianity.”
With the rise of the Reformation, the establishment of many denominations made the church more diverse, but it also brought divisions. Different denominations such as Lutheranism, Reformed Christianity, Anglicanism, Methodism, and Baptistism each declare their own beliefs to be true Christianity, and each interprets the meaning of "church." These differences not only affect the religious practices of believers, but also lead to different views on religion in society.
Regardless of tradition, the church has always been seen as a place for believers to grow spiritually, a pursuit that seeks to establish authentic relationships with God and each other. The church is not only a social organization, but also a spiritual family that supports each other and jointly pursues the practice and perfection of beliefs.
"The church exists to promote mutual support among believers, mold souls, and grow together."
Thus, for Christians, church means more than belonging to a particular denomination. Rather, it is about recognizing that this sacred community is built on a consensus of faith that transcends cultural and historical boundaries. Every member of the church is a supportive partner in each other’s journey of pursuing faith.
So, in the face of church diversity and spiritual challenges, how should believers understand and position their faith community?
