The Johannine community is an ancient community of Christian followers who positioned themselves harshly against the Jews. There are two notions of the Johaninne community that are reflected in John chapter 4:2 [Though Jesus himself baptized not, but his disciples].
The first notion reflected in the chapter is that the Johannine community put great emphasis on Jesus Christ’s teachings, predominantly those written in the Gospel of John. Their communal life comprised ritual activities recognized by other followers of Jesus Christ, but they drew attention to on the distinctive spiritual value of these rites. Baptism is an ordinance that Jesus Christ introduced to the church prior to his ascension. Jesus ordered
his followers to baptize people in the name of the Father, the Son, and the Holy Spirit, and to teaching them to follow all that He demanded them. These instructions stipulate that the Johannine community was committed to convey the teachings of Jesus Christ, recruit followers, and baptize those followers. So, the Johannine community performed baptism primarily because Jesus Christ commanded it.
The second notion reflected in the chapter is that the Johannine community manifests a concrete sense of fellowship, union, and cohesion. Also, the chapter brings out the true humanity of the Johannine community because its members are interested in people. They take time to mingle with the followers of Jesus and they occupy themselves with the arrangements for baptisms. Such events clearly highlight the crucial character of their concern for people. Baptism is a powerful ceremony that gives individuals a new identity, unites them to new communities of believers, initiates them into a fresh way of life, and offers them a clear mission in life.
