That is the buzz word accusation, for which the
Bishop of Ciudad de Este is suspended, so typical of the abuse of ecclesistical authority these days.
There is no apparent canonical crime; but a severe canonical penalty is imposed. The one in authority abuses his authority and unjustly disciplines the one who is vaguely accused of who knows what and then blames the accused for getting angry (and perhaps complaining) about the irregularity involved in his own case and requesting due process!
Since when is injustice less offensive than "lacking charity"? Charity is a gift which might not be given, without any implicit offence. Besides counterfeit "charity" abounds which is often contrary to right worship (cf. John 12:1-6)! Justice is the more basic virtue and the violation of it is a sin, and anyone who is guilty of it will answer before God, as the presumably innocent Bishop has rightly said.
Injustice is the greatest lack of charity!
If my defense and promotion of the honor of God should offend you, that is no lack of charity but actually the source of all charity: the love of God is the essence of charity.
