Please document or provide internet access to documentation of the
religious affiliation (Roman Catholic, Malankar Catholic, Episcopal,
etc.) of St. Antony's Church, Vaddy Kollam, PO Box 691,013 Kerala
India?

The only reference I can find to a St Antony's Church at this address
is in two letters pages in the BC Catholic ("the official newspaper of
the [Roman Catholic] Archdiocese of Vancouver)
<http://bcc.rcav.org/paper.htm>.

There are two letters, in the issues of February 12, 2001 : Catholic
recycling <http://bcc.rcav.org/01-02-12/letters.htm> and March 25,
2002 : A chance to help <http://bcc.rcav.org/02-03-25/letters.htm>,
appealing for "spare rosaries, statues, medals, scapulars, used
Christmas cards, magazines, etc. Also please send ballpoint pens,
pencils, and other items to help our school children."

A check on various sites and in several church directories (eg
churchesinindia.com, malankaraorthodox.org, missionsindia.org and
others) finds no reference to this particular church.

Sorry I can't be more helpful, r2l

Diocese of Kollam (Quilon). They follow the Latin (Roman) rite, that
is followed by the majority of Catholics around the world.
