Above I just rebutted the silliness of still believing that all who are not Roman Catholic are damned. I stand by what I have written there.
But, to more directly answer the OPs question, Why belong to the Catholic Church...here are my thoughts today.
1. I believe that the Catholic Church is the closest we can
come to a continuous continuity of teaching, authority and custom going back to
the actual Apostles.
2. I believe the Consecration at the Mass is the very act
that Jesus Christ Himself commanded us to perform as His anamnesis until He
3. I believe that the Teaching on the nature of God, the
desired relationship of Man to God, and the norms of behavior we are called to
strive for, emanating from the Scriptures, Sacred Tradition and the Teaching
Authority of the Church represent the best wisdom humans have, guided by the
Holy Spirit, on down through the Ages.
4. I believe that the Catholic Church has the deepest philosophy
for living of any religion or philosophical school: the one that seems to work
best with human psychology in leading human nature to be the best self it can
be. But, it is also works for simple people. So, it is a religion for both
philosophers and children.
5. I believe that the Catholic Church also pitches a broad
tent for many philosophies to coexist peacefully, provided they concur in the
kerygma. So it is deep but also wide and could someday embrace most of the
6. I believe that the ceremonies, images, allegories, and
sacramentals of the Catholic Church touch the human spirit in a positive way
not as available in other religions. (The ceremonies that have stood the test
of time are, in my mind, better than the new inventions.)
7. I believe in the Cloud of Witnesses, good souls who have
gone before us, that pray for us even after death, and whose prayers can be
efficacious through the mercy of God.
8. I admire the inventions of the Catholic Church as
expressions of her concept of charity: the hospital, the university, the
monastery, the council, the fund for service to the poor, the formal method to
obtain forgiveness for grave sin.
9. I admire the many saints who have sacrificed their lives
to serve their brothers and sisters out of love for Christ.
10. Although the Catholic Church has made many mistakes, and
her hierarchs and devotees have at times behaved badly, nevertheless I believe that
the core of goodness and truth at the marrow of the Church is still in touch
with the Holy Spirit and will persist in some form to the end of time.
11. Although the Catholic Church has many family feuds
within it, I believe that there is hope that these will be healed some day,
bringing Romans, Eastern Orthodox, Protestants, and Evangelicals together in
unity of faith and worship. Admittedly, this may be a long time in coming.
12. Although the Catholic Church has at times dabbled in
Politics and Business (often to her shame), I am delighted to see a trend out
of these arenas and back to her traditional roles as teacher, evangelizer,
motivator, admonisher, confessor, sanctifier, and mediator between God and Man.
Politicians and businessmen need to hear what the Church has to say.
