So it seems the consensus is that it is POSSIBLE for Jesus to, or anyone for this matter, make a mistake without sinning AS LONG AS there is no negative or sinful response to the mistake; IE.. kicking the chair after tripping on it??

Do any of you guys know of where I might find a "Biblical" definition of the word perfect? I am trying to do a study and the idea of being perfect and more Christlike but I can't find any solid "definitions" if you will, or any place that specifically talks about being perfect OTHER THAN saying that God and Jesus are both perfect and separated from sin.
