ἐν ἄλλοις τισι δυνάμεων ἐνεργήμασι.  The Benedictine translation is in aliis miraculorum operationibus.”  It is of course quite true that δύναμις is one of the four words used in the New Testament for miracle, and often has that sense, but here the context suggest the antithesis between potential and actual operation, and moreover non-miraculous (in the ordinary sense) operations of the Spirit need not be excluded; in a deep sense all His operations are miraculous.  ἐνέργημα is an uncommon word, meaning the work wrought by ἐνέργεια or operation.
