I think Msgr Perez got his title from a bishop in the state of Kerala , India.  And he'd probably say that St Thomas the Apostle gave them permission to issue honorific titles. How else could he have done so?
 

This is not the biggest issue in the world but a bishop can't just give someone the title. It ultimately has to be approved by the Pope...whatever. 

Right. That is Sacramental Theology 101.
Also Msgr. Perez is not a bishop but was somehow given this honorary title by some bishop in India. That makes no sense because only the Pope can give such titles. You can't just make things up because there is a crisis. Similarly, and I don't mean this out of disrespect to the dead, but I never understood how Fr. Leonard Giardina was called an "Abbot" when he was never installed by the Pope. I digress though...

An Indian bishop incardinated Fr Gruner into his diocese knowing full well the impossibility of Gruner obtaining a visa to live and function as a priest in his diocese. 
Traditional Catholic Bishops are least ensuring that people get valid sacraments. 

You have gotten off the topic here. The original question was,

What do you know about bishop Tom Sebastian of the SSCR?  I have recently learned about him, and would like to know what your experience if any has been with him.  I am getting mixed results from my research.


I went to the web site, The Oratory of the Immaculata and it says:
,
His Excellency, the Most Reverend Bishop Thomas J.F. Sebastian, SSCR, is the Founder and Prior General of the Priestly Society of Christ the King. Born on May 13, 1963, and raised in Southern California, he attended Saint John's Seminary College (for the Archdiocese of Los Angeles), then continued his studies at Mater Dei Seminary in Omaha, Nebraska. In response to a true and real need, His Excellency accepted the call to the Episcopacy and was consecrated in Kent, England, on the Feast of Saint Matthew, 1997.
 
The Oratory of the Immaculata web site does not give the name of the bishop who consecrated Bishop Thomas J.F. Sebastian, nor the church where the consecration took place.

Does anyone have this information please?

Stay far away from him. He is weird. I have met him in person, and so have some of my friends. 

He has been known to threaten anyone with a lawsuit who reports anything bad about him. Hence, the silence.

All my friends who have associated with him and who have attended his Masses and retreats have now deserted him. That should speak volumes.

We aren’t talking about whether or not the Duarte-Costa line is Catholic.
The accusation is that the lineage is not VALID.
SHOW ME HOW IT IS NOT VALID.  AGAIN THIS IS NOT ABOUT THE CATHOLICTY.
Am I clear?

It could be that the Da Costa line is valid, but they are not Catholic.
However, if their line includes the ordination of women to the priesthood or the episcopacy then that placess their validity in question. 

I saw on the Tradito Latin Mass Directory that a bishop(!) offers a TLM near my house. I went to the web site http://www.sscr.org/ It looked like it was from 1999 and was vague about the background of the organization and clergy. It says that he was "born and educated in Los Angeles" and "consecrated a Catholic bishop in Kent, England in 1997". This is irrelevant information for people who want to ensure validity. I recently emailed him asking for more information about himself. He didn't reply, which I find evasive. From what I've read in this thread, I'm glad I didn't go to that "Mass".

Trophy Club and Fr. Francis Miller OFM have competing chapels in essentially the same town.  And, Fr. Francis Miller OFM and his group travel quite a way for this "mission" chapel.  It is a large, long established, and lovely group of faithful.  So, all of those faithful prefer Fr. Francis Miller OFM coming in and renting a strip mall to Trophy Club.  I don't know why, but facts are facts.

Aside from the town in Texas, what is "Trophy Club"?
