Welcome, and congratulations.
You may find very helpful, particularly where you are now, the video series Dr. Sproul is offering on-line free, "What is Reformed Theology?" in the beta test of his new web site.
What Is Reformed Theology? Teaching Series by Dr. R.C. Sproul | Watch and Listen to Reformed Theology Teaching Series at Ligonier.org
This 12 lesson series builds from a foundation of what reformed theology has in common with the church universal, with evangelicals in particular, and then goes into reformed distinctives.
While we do share some truths in common with the Roman system, there are some essential differences that are absolutely life changing in terms of being discipled in the Christian life. Chief among them:
1) Justification by faith alone (which is the gospel)
2) The (supreme) authority of Scripture
There are other significant differences, but these two make much difference in the faith and practice of a believer.
As you understand this, you will have opportunity to refute the error of the Roman church in these central doctrines. But also remember, God has appointed your circumstances- and you will have access to people caught up in this. God will use you to engage those, with the difficulty and blessing that comes with that.
All to the Honor and Glory of our God!
