[Unam Sanctam]

If an indult mass is available but you choose to attend an SSPX service, then it would appear that your intent must not be simply to participate in a Mass according to the 1962 Missal for the sake of devotion. It is therefore not justified.

Nonsense. It is not a matter of rite only. It is a matter of devotion. The priest celebrating is crucial. What he teaches is crucial. How our children are instructed is crucial. You need to wise up.

"If an indult mass is available..."

I do not know of ultima's situation, however I have heard of indult masses with the words of consecration changed (pro multis to pro omnibus) and only the priest being allowed to communicate with a host consecrated at the indult mass. For the congregation, the priest is required to use hosts consectrated at a Novus Ordo mass.

I have not personally experienced this, but was told by someone who I trust who did experience this.
