I must apologise to the readers of this blog because I am going to be away at a theological conference until Thursday evening, which means I will not be giving a class on the Letter to the Hebrews to the novices. However, I have for them - and for you - a lecture given by Dr Margaret Barker that they can listen to while I am away. It is very, very interesting; and I would have published it here anyway, but with a youtube video by Dr Scott Hahn and a lecture by Metropolitan Kallistos Ware to complete the picture. I shall add the other two items when I return. All together they may well change attitudes to the Mass. I cannot rate this talk too highly. Putting it in my blog is the easiest way to give the students access to it.
