I'm just a layperson like yourself, and a recent (5 yr) convert, so I think I can relate to where you're coming from. For someone new to Orthodoxy, you are concerned with getting the "rituals" of the faith correct, for fear that the rituals themselves are connected with achieving God's Grace. Certainly, some rituals can be dark and lead us to sin, while others may lead us closer to God. However, I believe that consciousness of the ritual you are performing is an important factor in how it is percieved by God. If you are "trying you best," and practicing your faith with relative naivete, God overlooks the minor "goof-ups" of your Christian practice. However, we must always be vigilant in our Faith, and always seek to move closer and closer to God in our Faith. The knowledge that we gain on this spiritual journey will increasingly make demands of how we practice our Faith, and we are then bound by our knowledge to act increasingly Christian.
Let me put it this way: God knows our hearts, and knows our efforts and failures. THIS truth lies outside of the truth found in any individual religious ritual ("small t tradition"). Our redemption is not gained through legalistic means. We should try not to focus on the "small t" "traditions" of our Faith; rather, our focus needs to be maintained on the "LARGE T" Tradition of our Faith, which is none other than the Holy Spirit residing within us and within the Body of our Church.
I pray you find these words comforting, and that you succed in finding a spiritual Father in Prague. It sounds to me like you are on the right track.
your friend in Christ,
