Check out this conversation between Ligon Duncan, Al Mohler and Kevin DeYoung.
If I may be so bold, I see a "new, New Calvinism" taking root among those who hold to the Five Points of Calvinism to varying degrees, the authority of the Scriptures, a high view of God's holiness and sovereignty as well as His mercy and grace and the Five Solas of the Reformation (faith alone, grace alone, Scripture alone, Christ alone, to God alone be the glory!) but don't hold to the church culture and traditions normally associated with being "Reformed". It is that jettisoning of these church traditions that makes arbiters of "Truly Reformed" so incensed because in spite of the calls for semper reformanda, that only applies as far as constantly returning to the confessional standards in the eyes of the "Truly Reformed".
It is encouraging to see that so many people are embracing the Doctrines of Grace but see no need to cling to the traditions that surround it. These three brothers hold to those traditions but they have been profitable to learn from for many who don't. Our focus should be on the sovereignty of God in salvation, not on whether piano playing is allowed or the mode and recipients of baptism.
