These reflections are a translation of part 3 (on public confession) of 1891.16. Above the biblical citations with which each reflection begins, the translator placed a suitable heading. The small book with its apt title was just the right size to serve as a gift for youth making their public confession; the blue of its cloth binding may have been intended symbolically.
The subsequent undated reset edition (88 pp.) was published (as “second printing”) in a larger size (20cm.), but the blue binding was retained for all six printings (2nd edition: full cloth; next printings: paper binding, same size). The second through the sixth printings were published without any date. An extant, completed presentation page makes it clear that the sixth printing ($1.25) appeared in any case before 1960.
