Are we one?

Jesus said, The Father and I are one." Can we say that? Can I say, "I (John Bussone) and the Holy Trinity (The Father, Son, & Holy Spirit) are one?" Should I say that?

Does it frighten you to think about saying this out loud in front of someone? But wasn't that the point of Jesus' prayer, "that just as you are in me and I am in you, so they will be in us and the world will believe you sent me."

The reality of this prayer frightens me because Jesus made a lot of people mad when he said things like this.
