It has been supposed by the Benedictine editors that sane may be a misreading for salis. Whether that be or be not the case, the sacramentum intended here appears to be the sacramentum salis, in reference to which Neander (Church History iii. p. 458, Bohn’s Translation) states that “in the North African Church the bishop gave to those whom he received as competentes, while signing the cross over them as a symbol of consecration, a portion of salt over which a blessing had been pronounced. This was to signify the divine word imparted to the candidates as the true salt for human nature.” There is an allusion to the same in the Confessions (i. 11), where Augustin says, “Even from my mother’s womb who greatly hoped in thee, I was signed with the sign of His cross, and seasoned with His salt.”
