Jesus primarily came to save us from our sins, so we call Him Savior and Redeemer. As priest, He offered Himself on the cross in an act of sacrificial love. He was also a prophet, so he taught for three years before He went to his Passion and Death on Good Friday. The message of Christ was one of mercy and forgiveness. Most of the parables Jesus told had a message about the importance of being merciful and forgiving to one another.
He also commanded His apostles and disciples to preach the Good News (i.e., “the Kingdom of Heaven is at hand”). From that time on, sanctity and holiness became available to anyone and everyone who freely accepted and cooperated with divine grace; this is still true today. Christ’s death redeemed human nature and made it possible for human beings to receive sanctifying grace which comes from the sacraments. He told His disciples in Matthew 28:19 to go and make disciples of all nations and baptize them “in the name of the Father, and of the Son, and of the Holy Spirit.”
The bottom line is that Jesus not only opened the gates of heaven and made paradise once again possible to humankind, He also provided the means to become holy and therefore get to heaven. He also said in Luke 9:23, “If anyone wishes to come after me, he must deny himself and take up his cross daily and follow me.” Christianity is not a religion of taking advantage of what was done in the past, but an opportunity to imitate Christ and follow Him on earth and up into heaven.
The mission of Christ to sanctify (as priest), to teach (as prophet) and to lead and rule (as king) is continued in the mission of the Church via the seven sacraments (that make us holy), her Magisterium (the Church’s teaching authority), and the hierarchy (the pope and bishops who are successors to Saint Peter and the Apostles, respectively).
