Dear Kirkhaven,
Many Catholics would contend that what they hold is a developed understanding of the Faith once received; for us, that is a question we have not asked, but much of what the Catholics hold is compatible with Orthodoxy; there are a few real sticking points, of which the Papal claims are the most difficult. But if they are tour nearest Apostolic Church, then make contact and talk to the priest there. It may be the answer for you, or it may be a stepping stone towards Orthodoxy; let the Spirit lead you.
At the same time, go and experience an Orthodox liturgy. Sometimes, for those from a Western background, Orthodoxy can be very 'ethnic' (as some Orthodox congregations are); as I say, I have always found my Egyptian brothers and sisters so welcoming; but I know it is not always so.
What matters is that you grow in the Faith, and as you have found, the Church Fathers and the traditions of the Church are great guides in deepening one's faith. The fellowship of an Apostolic Church is also invaluable, for we are saved together in the body of Christ.
Do read my signature, it expresses what I believe. I know I have found in the Coptic Orthodox Church the fullness of the Faith, but I cannot know where else the Holy Spirit abides; God knows who His own are. You, too, will know when you find them.
peace,
Anglian
