To the above, which is an excellent contrast, I would add the following. The process of formally entering the Catholic Church for adults is called RCIA (Rite of Christian Initiation for Adults) and normally takes 6-12 months with formal "entry" into the Church occurring during the Easter Vigil Mass. While the quality of RCIA programs can vary substantially among Catholic Parishes and Dioceses, I believe there are some very healthy common threads:
1) Entrance into the Catholic faith must be a free-will, informed decision. There is no coercion. In some cases people withdraw from the process entirely and they are never ostracized or threatened with "the judgement of God" for so doing. In other cases, some folks repeat the RCIA class prior to making their final decision to enter the Church.
2) The RCIA process is about teaching the distinctives of the Catholic Church and its history NOT about judging the validity of one's own "personal relationship with Jesus". Other Religions and especially other Christian communities are respected. While some of the differences are highlighted during the process, the focus (at least in my experience) is about preparing to be Catholic NOT on slamming the group that you may have departed from.
3) The Catholic Church does not present its "doctrine" as "having all of the answers" for personal, marital, or family needs. For example, members (and potential members) are encouraged to learn Philosophy, History, and embrace sound psychological help if needed -EVEN when these things reveal some of the darker parts of Catholic history.
4) Diversity in viewpoints is tolerated. To be sure there are some sub-groups that are "far to left" and "far to the right" in the Catholic Church and some of the most extreme groups can hold points of view that are very intolerant and in the worst cases mind-numbing. However, on the whole, at the Diocesan level where the vast majority of Catholics live out their faith, there is a great deal of freedom and "normalcy".
5) Advanced education, philosophy, art, literature, fine wine, dance, and great music are all part of the Catholic experience -even at the Parish level. Catholics know how to live!
6) There is no ambiguity about what the Catholic teaches on all critical matters of faith and morals. Anyone can consult the
Catehcism of the Catholic Church and learn exactly what is taught. The Catechism is academically sound and heavily footnoted with copious references to Holy Scripture, Church History, Theologians, and Church Councils.
7) The Catholic Church is universal and very diverse in its membership with respect to racial, national, and socio-economic demographics. Yet the Catholic Church is focused on the locale. In the Catholic faith the "geo-graphical will of God" is where YOU LIVE, unless of course you are (by your own free will) part of a special religious order and you have taken vows of obedience. Otherwise, you are free to pursue the location that is best for you own family and personal economics, etc.
