First I'd say that since entire volumes have been written on the subject, one cannot come close to a complete answer in a brief post...so here goes

:
1. Christianity (also known as the
catholic - with a small "c" church) is the most logical answer to the question "Where has God revealed special revelation to mankind?"
2. Further, the Catholic (with a
capital "C") Church is the most accurate representation of Christianity as it is described in the New Testament and worked out by the following generations of Christian leaders. That is, it best represents the historic Christian faith.
That is my opinion with the full intent of not degrading or demeaning any other faith.
As for a brief summary, The Apostles Creed:
1. I believe in God the Father, Almighty, Maker of heaven and earth:
2. And in Jesus Christ, his only begotten Son, our Lord:
3. Who was conceived by the Holy Ghost, born of the Virgin Mary:
4. Suffered under Pontius Pilate; was crucified, dead and buried: He descended into hell:
5. The third day he rose again from the dead:
6. He ascended into heaven, and sits at the right hand of God the Father Almighty:
7. From thence he shall come to judge the quick and the dead:
8. I believe in the Holy Ghost:
9. I believe in the holy catholic church: the communion of saints:
10. The forgiveness of sins:
1l. The resurrection of the body:
12. And the life everlasting. Amen.
