Krima is the subject-matter of which a person had to be accused. They set up the krima of the Lord on the cross; that for which he came into accusation -- the charge. So it is used here.

Diakonos, 'servants' or 'deacons:' see Rom. 16.1 and 1Cor. 4.1.
Diakoneo, to serve, as servants or deacons.
More quickly than the writing of the letter supposed; but in case he delayed he wrote. The verse refers to his fears of being delayed.
