From a different drishtikone:
Vijay was trying to build a political base and his following was increasing.
And BJP perhaps suspected the role of Church in this and wanted to expose it and put a check on Vijay's ascendancy.
Mersal presented an opportunity to start that denouement dramatically.
Now Joseph Vijay being the truth and the Tamil viewers coming to know of it -- so far it was carefully hidden--we can expect that Vijay's following may take a critical look at the situation and some may decide to desert him.
And BJP scores there.
In BJP such strategies are carefully discussed and then only implemented. They do not react at the spur of the moment.
