John Gill Commentary 1 Corinthians 5:3

"For I verily, being absent in body but present in spirit, have already as though I were present judged him that hath so wrought this thing," — 1 Corinthians 5:3 (ASV)

For I verily, as absent in body
As he really was, being now at Philippi, if any dependence is to be had upon the subscription of this epistle; or rather at Ephesus; however, wherever he was, it is certain he was not at Corinth:

but present in spirit ;
in his affection to them, care of them, and concern for their good, and the glory of God:

have judged already ;
he had considered of the matter, thought very deliberately about it, and was now come to a point, to a determination concerning it, what to do in it:

as though I were present ;
upon the spot, in person, to do what he had resolved upon:

to him that has so done this deed ;
this infamous one, and in so scandalous a manner, and which was continued in: what that was which the apostle, upon mature deliberation and judgment, determined to do with this wicked man, is expressed in (1 Corinthians 5:5) which is to be connected with this, the whole fourth verse being to be read in a parenthesis, and that was to deliver him to Satan.
