That's awesome. But if you had forgiven them you would have covered their sins; not announce them.
And sin must be called out so that those who might be inclined to commit it in the future might take warning and think twice about committing it.
It is not that I have not forgiven them...my hope is that they will go to heaven.
But as for discipline and chastening and scourging in this life...that is not out of the question.
