The New Testament Textual Criticism blog posted this link to Dan Wallace’s course on the basics of New Testament textual criticism. It was created under the auspices of the Center for the Study of New Testament Manuscripts (CSNTM), Dan Wallace’s non-profit. Here’s the iTunes description:
Textual Criticism remains today as one of the most overlooked disciplines in Biblical studies. In this collection, Dr. Daniel B. Wallace of the Center for the Study of New Testament Manuscripts (CSNTM) teaches people from the lay to the scholarly level about the basic principles and practices of New Testament Textual Criticism (NTTC). Dr. Wallace defines New Testament Textual Criticism and discusses topics like identifying textual variants, categorizing manuscripts, and interpreting the available evidence.
There’s really no better resource for learning about textual criticism — highly recommended.
