I was born and raised Roman Catholic .Assuming that the author was baptized a Catholic, then, yes, he is still a Catholic.
I was born, baptized and raised Roman Catholic as well. I reject the claims of the Pacapy as being the chief shepherd of Christianity.
Am I still Catholic?
Yes.
(You may reject that label all day long, but in the eyes of the Church you still are one)
Perhaps the real question should be, am I fully Christ’s?
Personal pursuasion vs’ actual reality can be mutually exclusive.
It is true we are not to abandon the “gathering together” “as is the manner of some” but we go where we bear fruit.
A true ‘spiritual church of Peter’, would show all manner of spirtual fruits, love, charity, kindness, and new converts as the Holy Spirit saw fit to convict and transform. There would be timely, active and forceful means to put down sin amongst its leaders as well as amongst its laity. There would be no suppressions of the spirit should the Spirit decide to directly visit a congregation with manifestations of tongues(with translations), miracles, healings, and prophecies (though all these would need to be tested against the orthodoxy of scripture should any false doctrines arise and these manifestations found to be satanic in origin).
A true church of Peter would be longsuffering and able to persevere and even thrive under societal pressure and persecution. A true church of Peter would be an out post of Christ in a darkened world, manifesting his glory and the power of his resurrection and yet a true church of Peter is also the whole of all present and past and future believers. For the church that Peter would call his own, would be the church and Bride of Christ..as would all apostles and prophets proclaim as well!
This body, this true “catholic” body(small c), is a people drawn from all nations, tongues, and circumstances. They may be of Catholic, Orthodox , or protestant pursuasions but all have had an encounter with Jesus Christ apart from how the traditions of their various back-grounds have colored their thinking. There is the word, there is the application and teaching, but then there is the man and God Christ Jesus himself....”behold I stand at the door and knock....!”
So lets refine your question...It is not, “am I still Catholic”, but rather...”Am I really a part of the catholic body of saints, ruled by Christ and infused by the Holy Spirit?” (Or in short “Am I fully Christ’s?”)
