Dec 4, 2015
Dear Mass Attendees of the Denver, Colorado Mission,
I am aware that on Sunday November 22, 2015, the Coordinator of the Mission where you attend Mass, hosted Bishop Ambrose Moran to celebrate “Mass” for you. I do not have sufficient evidence to prove that Fr. Joseph Pfeiffer approved of this. I have not been able to get a hold of Fr. Pfeiffer to determine whether he did approve or not. I did, however, get in contact with the Coordinator via e-mail last week and he agreed to speak to me over the phone. Unfortunately, the phone call did not occur and I have not been able to get a response from him since. My intention was to warn him that Bishop Ambrose Moran was consecrated a bishop by schismatics, for which he has never publicly repented, and that Bishop Ambrose Moran was lying by claiming that he was a Catholic bishop. See my posts here, here, here, and here. Therefore, I wanted to exhort the Coordinator to desist from hosting Bishop Ambrose Moran anymore. Unfortunately, it seems that the Coordinator may be hosting Bishop Ambrose Moran again on Sunday December 6, 2015. Therefore, I want to warn you that if you actively participate in Bishop Ambrose Moran’s “Mass”, you will be committing, objectively speaking, the sin of “communicatio in sacris”, which is a grave sin against the First Commandment. You may also be committing, objectively speaking, the grave sin of approaching doubtful sacraments.
You may contact the Coordinator at olmcdenver@yahoo.com to raise your concerns. You may also contact me, Tony La Rosa, at info@ecclesiamilitans.com if you have further questions.
If anybody knows of persons who attend the Denver, Colorado Mission, please notify them in your charity.
