No one said they were necessary for salvation?

Eucharist: "Unless you eat my flesh and drink my blood you have no life within you." 

Baptism: Mark 16:16 “He who believes and is baptized will be saved; but he who does not believe will be condemned.”

John 3:5 “Jesus answered, ‘I tell you the truth, unless a man is born of water and of the Spirit, he cannot enter the kingdom of God.’”

Confession: "Whatever you hold loosed on earth is loosed in heaven and whatever you hold bound on earth is bound in heaven."

So yes, someone said that. It was Jesus.
