John Calvin Commentary Acts 20:37

"And they all wept sore, and fell on Paul`s neck and kissed him," — Acts 20:37 (ASV)

Great weeping. It is no wonder if all the godly deeply loved this holy man. For it would have been an act of profound ungratefulness to despise him whom the Lord had so adorned with so many excellent gifts. And the chief reason for their weeping was, as Luke notes, because they would see him no more.

For they lamented their own condition and that of the entire church of Asia—and not in vain—which they saw was deprived of an inestimable treasure. And when the Spirit commends their tears through Luke, as witnesses of sincere godliness, He condemns the rashness of those who require of the faithful a harsh and unfeeling composure.

For what they imagine is false—that these affections, which we have naturally from God, proceed only from corruption. Therefore, the perfection of the faithful does not consist in this: that they put off all affections, but rather that they are moved by them only for just reasons and that they moderate them.
