Thank you that answers my question, it appears that Christ saved no one while on earth.
John answered them all, "I baptize you with water. But One is coming who is more powerful than I. I am not worthy to untie the strap of His sandals. He will baptize you with the Holy Spirit and fire.
No it defitely doesn't appear that way. Christ is the owner of His sacraments, so nothing prevents him from remitting sins and give a new birth directly and not through sacraments of the Church. Secondly, Christ can -- and does -- act through people He empowered, in this case, to baptize.
