Question
Jesus said: "I and the Father are one" (Jn.10:30), therefore, is not Jesus the same, or, "co-equal" in status with his Father?

Answer
In Greek, `heis' means `one' numerically (masc.) `hen' means `one' in unity or essence (neut.) Here the word used by John is `hen' and not `heis'. The marginal notes in New American Standard Bible (NASB) reads; one - (Lit.neuter) a unity, or, one essence.
If one wishes to argue that the word `hen' supports their claim for Jesus being "co-equal" in status with his Father, please invite his/her attention to the following verse:
Jesus said: "And the glory which Thou hast given me, I have given to them (disciples); that they may be one, just as we are one." (John 17:22).
If he/she was to consider/regard/believe the Father and Jesus Christ to be "one" meaning "co-equal" in status on the basis of John 10:30, then that person should also be prepared to consider/regard/believe "them" - the disciples of Jesus, to be "co-equal" in status with the Father and Jesus ("just as we are one") in John 17:22. I have yet to find a person that would be prepared to make the disciples (students) "co-equal" in status with the Father or Jesus.
The unity and accord was of the authorized divine message that originated from the Father, received by Jesus and finally passed on to the disciples. Jesus admitted having accomplished the work which the Father had given him to do. (Jn.17:4)

Hot Tip: (precise and pertinent)
Jesus said: "I go to the Father; for the Father is greater than I." (Jn.14:28). This verse unequivocally refutes the claim by any one for Jesus being "co-equal" in status with his Father.
