Catholic Church is not a club. Among the first heresies the Church confronted and confidently put down was donatism, a belief that the church should restrict its membership to suffucuently holy people.

Are you saying there are no required beliefs to be a Catholic? That you can deny official Catholic dogma and remain a Catholic? That it is heresy to reject membership based on a particular belief or lack thereof?

I mentioned the "unchanged dogma of all ages", did I not?

The church can, and must, excommunicate her enemies. Her sacraments, nevertheless, are available to all capable of receiving them. For example, anyone can complete the rite of initiation and become Catholic, and anyone already Catholic who defies the dogma can confess, repent, and receive communion. Nothing places a sinner permanently outside of the church.
