The young visitor was quite excited to tell his parents all that he had been taught during his first visit to a Christian Science Sunday School. He started to describe to them some of the things the class had discussed during the hour, adding that they also talked about someone named "Myrtle Mind"!
When a friend told me this many years ago, it reminded me of some of the early impressions I had as a young Sunday School pupil about the terms mortal mind and error, which appear in Mrs. Eddy's writings. In hearing people use these terms, whether in Sunday School, in testimonies given at Wednesday evening services, or at home, I don't think I ever believed the terms referred to some one, but it may not have been as clear to me at first that they didn't refer to some thing either.
Though people often use these terms interchangeably, it's helpful to consider the distinctness of each in sharpening our work as Christian healers.
