Catholic catechisms and St. Thomas teach that a baptismal character (which is an indelible mark) does two things: 1) it marks us as belonging to Christ; and 2) it enables us to receive other sacraments. Summa, IIIa, Q.63.
Not feeling himself limited to Catholic Doctrine, Bishop Fellay expounds
the strange theory that the baptismal character also causes us to recognize
the goodness of the traditional Mass. Bishop Fellay says that,
when we attend the traditional Mass, there is a “click” [his word],
which is our baptismal character causing us to recognize that this Mass
is pleasing to God and is truly Catholic. Bishop Fellay then says
most of the time there is absolutely no
‘click’ with the new mass.
Quoted from Bishop Fellay’s
October 19, 2012 conference, sold by Angelus Press, disc 1, about minute
76 (emphasis added.)
Recently, Bishop Fellay reiterated his novel theory:
[Y]oung [conciliar] priests identify with this [Traditional] liturgy, precisely because it is timeless. The Church lives in eternity. The liturgy does also too [sic], which is why it is always young. Close to God, it is outside of time. So it is no surprise that the baptismal character makes this harmony resound even in souls that have never known the liturgy.

There are two problems with Bishop Fellay’s “click” theory:
Bishop Fellay’s comments are soft on the new mass, because his comments indirectly say that at least occasionally our God-given sacramental character (which supposedly helps us to discern what is good) will give a “click” in recognition that the new mass is good!
One supposes that Bishop Fellay would say that this (purported) “click” occurs when the new mass is used under the “best”, strictest conditions. But if the new mass is good under strict conditions, then the new mass is good in itself!
