The term Peter uses is a composite of two Greek words, with one referring to patterns of thought and the other referring to alike. Patterns of thought determine habits of conduct and hence lifestyle. Thus far in his letter Peter has drawn out what patterns of thought befit a Christ-centred worldview (1 Peter 1:3, born again to a living hope) and what patterns of conduct necessarily follow (1 Peter 2:11, as sojourners and exiles). As he ties things up, Peter now tells his readers to make a point of being homogenous in their thinking and hence in their acting. They need agreement, unity, alikeness among themselves as to the implications of what Peter has written.
