1752
The cross-shaped church completed
In 1752 the brick church was finished, built in the form of a cross and facing east toward the rising sun, the work begun by Fr Buttari and carried to completion by Fr Clement Thomassini. The parish's own history records that in Thomassini's time the great Feast of the Assumption took root here as its principal festival. Bertrand, writing from within the mission, gives this church a different titular feast: St Francis Xavier's, kept with a great novena every December.
In English
"Fr Thomassin, who came to occupy the post of Vadakencoulam, completed the building of the church, won the Christians by his patience, his gentleness and his humility, rooted out abuses and superstitions, and made faith, piety and fervour flourish in that Christian community."
What this source establishes
The Buttari→Thomassini hand-over and the completion of the church — the one printed, documented thing in this dot. Bertrand's own volume records that the titular feast of this church was ST FRANCIS XAVIER'S, kept with a December novena, right up to the re-dedication of 1872.
