Socrates4Jesus said:
"…be perfect, just as your heavenly Father is perfect." (Matthew 5: 48 New American Bible)
…answer this question…: “Have i ever obeyed this command?” If you have, please explain how.
Good question. I guess I’d first like to know how you would define perfection, but I’ll go ahead and address the issue from my understanding first.
First, I have always been concerned with using single verses as quotes to make a point. Modern translations (including the NAB which you used) try to use english conventions of sentences and paragraphs and these do not always match up to verses. In this case Matthew 5:48 is a part of a larger paragraph in the NAB (5:43-48) that admonishes us to love our enemies and pray for those who persecute us.
Is Christ defining perfection as loving one’s enemies and praying for those who have persecuted us? In that case I can answer your question yes. Although, I have clearly admitted to having trouble with this command (I’ve sinned) I have had moments and even longer periods of time where I was perfectly at peace with this command. Most often and most completely after the Sacrament of Reconciliation, where I was able to talk out my feelings, here a gentle admonishment and word of encouragement, and spend time in prayer doing a pennance. Again, if this is your definition then I’d say the answer is yes.
Is Christ more generally saying that perfection is doing exactly what God wants us to do? If so then, while I admit to messing up a lot, I can still answer yes I have obeyed this command. I had myself and my family Baptized according to church Tradition. Is there more I could have done to obey the command to be Baptized? I don’t think so, so I guess that was perfect obeyance. I have received the Sacrament of Reconciliation for mortal sin and try to go regularly for venial sin. Sinning is obviously not perfection but is there more I am to do, according to Tradition, than seek and ask for forgiveness? Not that I know of so I assume I am doing exactly what God wants. Again according to this use of the word Perfect, I am obeying God.
Third, I note that perfection is used in this way only in this verse and in Matt 19:21 If you read Matt 19:21-26 you see what I think is a clearer explanation of perfection. Jesus acknowledges we are to be perfect but that without God it is impossible. I don’t see here a declaration that allows us not to strive for perfection, but rather an acknowledgement that even our perfection will be imperfect.
Finally, the parallel to the original passage in Luke replaces the word “perfect” with “merciful”. Does perfect mean merciful? Again, I have not always shown mercy when I should (I’m afraid I sin a lot), but I have shown mercy. This particular issue is a bit personal for a public forumn but if you define mercy as not exacting from someone that which I legally had a right to, then the answer to your question is still yes.
