McCarrick resigned from the College of Cardinals in July amid fallout from an Archdiocese Review Board investigation into allegations he abused a teenage altar boy while he was a priest of the Archdiocese of NY.
The Vatican will gather senior bishops from around the world later this week for a conference on sex abuse created to guide them on how best to tackle a problem that has decimated the Church's credibility, but critics say it is too little, too late.
The global organisation Ending Clergy Abuse (ECA) said that the church's promise for "zero tolerance" towards abuse is an empty one, without the removal of not only clergy abusers but also those who cover up for them.
Despite the apparent common knowledge in church circles of his sexual behavior, McCarrick rose to the heights of church power.
McCarrick resigned as a Cardinal in July.
He noted that, even today, "there are many who propose themselves as dispensers of happiness": They promise success in the short term", Pope Francis said, "great profits to be had, magical solutions to every problem, and so on.
How does this fit into the wider sexual abuse scandal?
The organization, which brings together activists and survivors from more than 17 countries, said any cleric found to have abused a child or covered up abuse - regardless of how long ago the crime took place - should be defrocked.
His account of being abused helped the Boston Globe produce a Pulitzer-winning investigation into church cover-ups, which was chronicled in the movie "Spotlight".
Survivors of sexual abuse by priests and clergy stand before photos of accused religious men during a news conference on February 14, 2019, in New York City.
Francis' move marks a remarkable downfall for the globe-trotting powerbroker and influential church fundraiser who mingled with presidents and popes but preferred to be called "Uncle Ted" by the young men he courted.
The Pope has defrocked the former United States cardinal Theodore McCarrick, making him the highest profile figure to be dismissed from the priesthood in modern times. A church trial found him guilty of sexually abusing minors.
Mr Grein said the abuse began when he was 11 and continued for decades.
He adds he hopes that McCarrick will no longer be able to use the power of "Jesus' church to manipulate families and sexually abuse children".
DiNardo's handling of abuse cases in Houston has come under question. His appointments included: auxiliary bishop of NY, bishop of Metuchen, archbishop of Newark, and archbishop of Washington.
Complaints were also made about McCarrick's conduct in the New Jersey dioceses of Newark and Metuchen, where he previously served.
Vigano then accused Pope Francis and several of McCarrick's close friends, including the archbishop of Chicago, Cardinal Blaise Cupich, of knowingly "rehabilitating" McCarrick's image, ignoring Pope Benedict's sanctions, and welcoming McCarrick back into the fold of high level Vatican administration. The lawyer said his client, who was about 16 at the time and a student at a Catholic high school in NY, pushed McCarrick away.
