1745
The catechist and the nabab
The same year brought the church its own trial. Vadakkankulam then depended on the mission of Néman, and a brahmin led the pagan governor to demand a contribution for a temple. The catechist refused, and was tortured with the kittei — his fingers crushed between two blocks of wood until the blood sprang from the nails — while the neophytes' houses were pillaged. Fr Buttari at once sent two Christians with a letter to the nabab "on whom Vadakkankulam depended, and who honoured him with his friendship." The lord sent a commissioner with orders to protect the Christians thereafter, and the priest, Bertrand records, "found himself surrounded with respect and awe."
In English
"Fr Bouttari, who baptised Devasahayam… He administered the Christian community of Vadakencoulam and laid the foundations of its present church; he left that country to replace Fr Thomassin in the district of Aour."
What this source establishes
The documented core, and all of it: Fr Buttari "laid the foundations of its present church". Bertrand gives NO year. The 1749 date, the kankol festival and the fabric of the building are all parish-side — which is why this dot is tiered tradition, not documented.
