This means the refusal to come to the sources of Redemption, which nevertheless remain "always" open in the economy of salvation in which the mission of the Holy Spirit is accomplished. _ Blasphemy against the Holy Spirit, then, is the sin committed by the person who claims to have a "right" to persist in evil-in any sin at all-and who thus rejects Redemption. One closes oneself up in sin, thus making impossible one's conversion, and consequently the remission of sins, which one considers not essential or not important for one's life. This is a state of spiritual ruin, because blasphemy against the Holy Spirit does not allow one to escape from one's self-imposed imprisonment and open oneself to the divine sources of the purification of consciences and of the remission of sins. (Papal Encyclical, Dominum et Vivificantem, 18 May 1986).
