I have been reading the academic journal Themelios for years with great profit. Recently it went online for free after a long time of being a print journal. In my mind, Themelios is one of the great evangelical journals available today alongside Evangelical Quarterly, The Trinity Journal, Tyndale Bulletin, Eusebeia, Westminster Theological Journal, etc.
With this change to online status (including archived back issues!), Themelios also has a new editor: D.A. Carson. Thankfully, Carl Trueman is still involved in an editorial role. These two scholars together make this journal a must read.
The second online issue is now available here. The main website for the journal is here. Make sure you bookmark this site and check it regularly!!!
