“The Christ” is Jesus’ title, not His last name.
The title means “The Anointed One—“ anointed to be King. Even before He died, He was already training His disciples how to receive and minister to people as “anointed ones”—Christians, and the believers came to be called. The anointing described in John 14-16 is aimed to produce in us the same intimate love between the Father and the Son that Jesus Himself experienced (John 17). Stepping into this relationship with Father God can be especially healing for people whose earthly dads failed to love them—or even abused them.
