Final answer:
In the baptism of Jesus, unique aspects such as the descent of the Holy Spirit, the voice of God, and the context within the Jordan River set it apart from modern Christian baptisms. These supernatural occurrences and historical settings are not shared in personal baptisms that signify the entry into the Christian community and commitment to its teachings.
Step-by-step explanation:
In your baptisms, what do you not have in common with JC? This question reflects the unique aspects of the baptism of Jesus Christ (JC) compared to Christian baptisms today. In the Baptism of Christ, several distinctive elements are present which individual Christian baptisms do not share. Firstly, during the baptism of Jesus, it is recorded that the Holy Spirit descended upon Him in the form of a dove, which is a unique event signifying the divine approval and anointing of Jesus's ministry. Secondly, the voice of God the Father was heard, declaring Jesus as His beloved Son, setting His baptism apart as a divine endorsement. Lastly, the setting of the baptism, in the Jordan River, and the attending figures like John the Baptist and personified elements such as the river itself, are specific to that singular event.
Comparatively, common Christian baptism practices today do not involve these supernatural occurrences or the same historical and geographical context. Christians believe baptism signifies the washing away of sin, entry into the faith community, and commitment to a life following Christian teachings. However, unlike Jesus's baptism, which was a proclamation of His divine sonship and mission, a Christian's baptism does not confer nor signify a divine identity or mission. Furthermore, although some Christian traditions emphasize the use of 'living water' for baptisms, this practice is not universally followed, nor does it entail any divine vocal affirmation as in the case of Jesus.
In summary, while Justin Martyr contended that Christian baptisms were distinct from pagan purificatory rites in that they did not transform one into a permanent member of a new religious community nor were regularly enacted upon entering sanctuaries, the baptism of Jesus remains distinct from both Christian and pagan rites in its unique divine phenomena and contextual elements.
