"Anyone can claim (anything)," Sebastian said when asked about the claims of the nun's family.
Archbishop Couto was not available for comments.
The vicar general said the archbishop was out of Delhi and would be back by the weekend.
In her complaint to Kottayam District Police chief, the nun has charged the bishop of the Jalandhar diocese of Roman Catholic Church with rape and unnatural sex multiple times at a small town near Kottayam in Kerala between 2014 and 2016.
