Nobody said it wasn't apostolic. Do you understand the difference between a pious saying and dogmatic truth? Here's a favorite saying of my own: "If a pope does not teach Church doctrine, do not follow him."--Pius IX.
Did Pius IX also say to start your own Church? That's all I'm getting at.
Leaving the Church (and you have) and encouraging others to do the same is not what Bl. Pius IX or St. Athanasius had in mind. You can dissent right in the Church.
If you can't bring yourself to go to an Authorised Mass at least once a year and receive Communion, then you have indeed left the Church. Is the indult Mass so odius to you. I know it is to the devil.
