I started to work on my first actual post on one of the five points of Calvinism but thought I would go ahead and list a few resources that you can go to for more information.
For those who may not be familiar with the Five Points of Calvinism these were formulated at the Synod of Dordt in 1619 in response to what is known as the "Five Articles of the Remonstrance." They have taken the form of the acrostic TULIP. These stand for:
T - Total Depravity
U - Unconditional Election
L - Limited Atonement
I - Irresistible Grace
P - Perseverance of the Saints
Here are some online resources.
There are several good resources at the Center for Reformed Theology and Apologetics.
Canons of the Synod of Dordt - this is the original formulation.
The Reformed Faith - an online book by Loraine Boettner.
The Five Points of Calvinism - an online book by R. L. Dabney
A Defense of Calvinism - online book by C. H. Spurgeon
The Five Points of Calvinism by Herman Hanko, Homer Hoeskema, and Gise J. Van Baren. This is particularly helpful for those who want a continantal perspective on the five points. These authors are from the tradition of the Heidelberg Catechism, not the Westminster Tradition. They show that the Heidelberg Catechism and the Canons of Dordt are two parts of one whole and that the five points are inherent in the whole continental/Heidelberg tradition. Thus, even though the five points aren't discussed as explicitly in the Heidelberg Catechism as they are in the Westminster Confession, they work together with the Canons of Dordt and are foundational to the whole tradition.
And of course the mother lode can be found at Monergism.com.
By His Grace and For His Glory - by Tom Nettles. This book, written by a Southern Baptist was the most influential book in my own study of Calvinism. It was particularly influential for me because I read it while still as Southern Baptist. A great book for anyone who says that you can't be a Baptist and a Calvinist (which I have heard).
Chosen by God - an outstanding exposition by R. C. Sproul
Of course there is a whole lot more, but for those who want to study such things, those will get you started.
