Why am I Catholic? The simple reason is because I have been confirmed in my Faith. That doesn't simply mean the I went through the Sacrament of Confirmation (which I have), but that by the grace of God, by Faith is firmly established in the Catholic Faith.
I have a deep respect for my Eastern brethren (and I truly see us as brothers), but in those areas where there is a divergence of views (i.e., Papacy) I firmly adhere to the Catholic viewpoint. Through my dialogue with the Eastern Orthodox, I certainly have learned a great deal of the Church Fathers (for which I am extremely grateful) I often tell my fellow Catholics that if they want to dialogue with Protestants that they had better know Scriptures inside and out, chapter and verse; but if they want to dialogue with the Orthodox, while still needing to know Scriptures, they had better know the Church Fathers and Councils inside and out. That education in the Faith of our Fathers is invaluable. And through my study (even more firmly than before), I have been convinced beyond a shadow of a doubt that the Catholic Church IS the Church.
I am a Catholic of the Latin Rite (though I attend Liturgy at various Eastern Rite Churches on a semi-regular basis) who is faithful to the Holy Father and the Magisterium.
Tu es Petros - and I stand with him!
