-Why must we return from the Nicene Creed to the gospel of the water and the Spirit? -

The gospel that the early church preached was precisely the gospel of the water and the Spirit. That gospel was the gospel that Jesus actually shouldered and washed away the sin of the world through the baptism He received from John.
The baptism Jesus received from John was to fulfill the law of the sacrificial system found in Leviticus. That is, just as sin was transferred to the sacrificial offering through the laying on of hands, the substance of that sacrificial law was fulfilled through Jesus`s baptism.
However, in the process of the Nicene Creed`s formation, the ministry of Jesus having the sin of the world transferred to Him by being baptized by John was deleted from the creed`s contents. As a result, this truth has been passed down in a hidden state within Christianity for about 1,700 years, reaching the present day.
Today, many people are struggling to receive the removal of their sins without knowing when their sins were transferred to Jesus. Because of this, even while saying they believe in the gospel of the cross, they fail to reach true assurance of salvation and live amidst repetitive repentance and the pangs of conscience.
The reason we must return to the gospel of the water and the Spirit is clear. This is because only this gospel allows us to meet the Jesus who became the sacrificial offering as the sin of the world was transferred to His body, and thereby have assurance of salvation.
