Remind them that;
a) The bible is quite clear on the topic of sexual immorality (sin)
b) Some/many unbelievers masquerade as clergy. (Not real priests)
c) A huge percentage of the unsubstantiated, unfalsifiable, hearsay accusations have never been tested in a court of law - why? Lack of evidence. Accused priest has died. Accuser eventually recanted.
d) The anti-Church zeitgeist hysteria directed by the sensationalist (atheistic) mainstream media at today’s Church leaders relates to events 20, 30, 40, 50 years old - alleged events over which today’s church leaders had no control whatsoever. In other words, innocent scapegoats. Moreover, for at least the last 10 years, the Church leadership bears no resemblance to the ‘bogeyman’ hierarchy depicted by its enemies. Transparency and meticulous scrutiny are now systemically embedded in every aspect of child protection in the daily Church life.
e) Lay parishioners are NOT accomplices and bear no guilt - no matter what disgraceful coverup action may have taken place. We owe no one an apology for the actions of other people.
f) The attacks on priests and slandering the many because of the deeds (done in darkness) by the few, must be seen they the lens of spiritual warfare. This is an attack by satan who knows that in order to scatter the flock you first attack the shepherd.
In my small diocese we’ve had three priests suspended, one convicted and in jail, in the last 18 months. I wouldn’t say that the “transparency and scrutiny” are so great. How did these three priests fly under the radar? The decriminalization of sodomy has put priestly misconduct in the ordinary category of being a 'weakness" instead of being something which automatically disqualifies them from active ministry.
Our bishop was totally blindsided by the problems with these three priests so I have NO confidence in the Church, top to bottom. There is no accountability. These priests and bishops are ordinary criminals covering up their crimes, walking around in plain view, until the rug gets pulled out from under them.
Regarding the title question, I’d say the Church has had misconduct problems from the beginning, including sexual scandals. Show me the Church with no sinners and I’ll take a look at it. Their’s are legitimate criticisms, but we are assured that Christ is with us.
