I don't believe I said that Old Catholics were a new group
However, they are very splintered, into multiple different sects, some of which are more serious and noteworthy than others. Some of them have actual long histories, parishes, parishioners, and stability. Others of them are basically episcopi vagantes who start their own group, give themselves exalted titles, and have about as many clergy as faithful.
Pretty much any group that offers quick ordination (and that advertises on their website how to become clergy) or that has an elaborate "apostolic succession" chart is a non-serious group. Facebook is full of such bishops, who have no real flock.
The Church is not the clergy and the clergy are not better than the laity. The clergy exist within the Church for the service of actual flocks.
In Christ,
Fr. John
