“Nope, the Blood of Jesus does that.”
The blood was necessary on the cross. It isn’t used in Baptism. Grace is. The blood of Christ on the cross is what created the grace. Perhaps you’ve never read Ephesians 1:7 before.
“Baptism is an outward sign by the believer that he is born again. It symbolizes being crucified with Christ.”
Baptism is an outward sign of an inward movement of grace instituted by Christ for our sanctification. Or:
“Sacraments are outward signs of inward grace, instituted by Christ for our sanctification (Catechismus concil. Trident., n. 4, ex St. Augustine, “De Catechizandis rudibus”).” http://www.newadvent.org/cathen/13295a.htm
“Therefore his/her sins have already been washed away.”
False. Remember, Paul believed in Christ from when He heard His voice on the road to Damascus. Yet it was only in Damascus, after instruction from Ananias, and his healing, that Paul was told, “Rise and be baptized and wash away your sins, calling on his name.” (Acts 22:16)
“By the Blood of Jesus, not water baptism.”
One in the same through grace as shown in Romans 6:1-4 and you have to have water: Acts 8:38.
God make it simple, Catholicism makes it complicated.
Grace, a free gift from God to the repentant sinner who is in Jesus and Jesus is in him/her.
It doesn't come at baptism.
