Here Jesus is talking to the Apostles"Simon, Simon, behold, Satan demanded to have you, (In Greek word for you is Plural) that he might sift you (In Greek word for you is Plural) like wheat, but I have prayed for you (In Greek word for you is Singular) that your faith may not fail; and when you have turned again, strengthen your bretheren." Lk 22:31-32
We see here Satan has demanded to test all of the Apostles. But Jesus says he has prayed only for Peter. So that Peter can "strengthen your bretheren"
This all seems quite odd if Peter does not have an authority over the other Apostles. Why would Jesus only pray for Peter if they are all equal? Why would Peter strengthen the others if there all equal?
