Being a catechumen implies that you are studying, in addition to praying, reading the Bible, and participating in divine services. Since you did not bring it up, please allow me to recommend some sources and books. (Of course, please overlook this advice if you have already started on a course of study about Holy Orthodoxy).
1. If your church has a formal curriculum, please follow it.
2. If not, I recommend you scour the Antiochian Archdiocesan Internet site as it is full of great articles and links.
3. Books by Frs. Thomas Hopko and Alexander Schmemann of blessed memory. Start with the more accessible ones (your church bookstore should have most popular titles).
May the Holy Spirit guide your studies.
