Looks like a rabbitt trail to me. Do you actually know what a spiritual gift is? Pauls actually lists them in one of his epistles. Do you really think scripture was talking about the gift of an office in some religious orgainization? I think not. Don't look like Paul is with you on this one.
Doesn't matter what the particular gift is. Paul said "the gift of God which is in you through the laying on of my hands." That means that a gift of God can be conveyed to someone through the laying on of hands, which I believe was the point.
For the record, I believe the gift to which Paul is referring is the guidance of the Holy Spirit to enable Timothy to faithfully administer the office of a bishop in the Church of God. But that is secondary.
