#68 and #106. The author conflates the crisis in the Church and the state of necessity, and while they are related - one is the cause of the other - they are also distinct as Fr. Knittel explained. By way of an example:
Consider a soul aboard the ill-fated Titanic. He learns of a priest aboard (Fr. Thomas Byles) who's hearing confessions, so he decides to go. However, this penitent confesses a reserved sin such that the confessor cannot absolve him, he must wait until they arrive in New York and have recourse to the bishop. That evening the iceberg hits the ship. Suddenly there is a crisis - the ship is sinking - and for this individual there is a state of necessity - he needs to be absolved. In such circuмstances (danger of death) any priest can absolve a reserved sin, so the penitent returns to confession. But while waiting his turn he spots an empty seat on one of the lifeboats and decides to make a dash for it. Sometime later a rescue ship, the Carpathia, arrives and picks up the lifeboat occupants. On board this ship there is also a priest (Fr. Henry Burke) hearing confessions, so the penitent again presents himself for confession. But he can no longer be absolved because there is no longer a state of necessity - the individual has been rescued and is safe - even though the crisis - the sinking Titanic - is still on going.
It should be obvious that a state of necessity exists only in a specific circuмstance and only for as long as that circuмstance persists. Within the Society the state of necessity certainly existed, like the need to consecrate bishops, the need to absolve and marry, the needs of the faithful to have access to the traditional Mass and sacraments But with the freeing of the Mass, lifting of the excommunications, and granting the faculties of confession and marriage the state of necessity has diminished. That doesn’t mean it will not re-emerge in the future, e.g. the need to consecrate bishops without a mandate or an uncooperative diocesan bishop insisting on a N.O. Priest celebrates the Nuptial Mass, but until that time there is no longer a state of necessity, but the crisis continues.
