The Masonic lies of Vatican II gave sɛҳuąƖ deviants control of the Catholic Church.  Mass and sacraments were weakened in order to destroy the Church from within.   Vatican ii opened the door to create liberal Catholics who go against God's Commandments.  The decline of Catholics started after Vaticanll.  Then the rapes and molestations of children and young seminarians increased.  Then the many who sinned with their silence and cover ups.   The hierarchy fails to repent and continues to lie and coverup with the closing and selling of Catholic Churches and catholic schools, relics, statues, cemeteries.  

Traditional groups within Vatican ll and outside have had their share of sɛҳuąƖ abuse by priests.  

Thanks to sspx and 1988 it forced the novus ordo to allow Latin mass.   However, the sspx and other traditional groups like cmri is that they didn't go out to convert others.
That is not Catholic.  

During the negotiations with Rome, the novus ordo went full speed ahead with Catholic Church and School closings instead of filling them with groups like Fssp or future sspx.

The novus ordo sold off shrine property to Non Christians who worship a false god.   And lacked charity towards sspx.

The deal with Rome was done and no turning back.  

The truth shall set you free.    

The four Marks is what makes the Church Catholic.
