I’m sorry but this does not sound like Catholic theology to me, especially about the last part that a state of grace is permanent. You answered my statement that one sin can indeed take you out of a state of grace by committing a mortal sin and if certain accusations against Fr. Corapi are verified as true then I think that would count.

According to the article on sanctifying grace in the Catholic Encyclopedia,sanctifying grace produces a permanent condition.

< Before the Council of Trent, the Schoolmen seldom used the term gratia actualis, preferring auxilium speciale, motio divina, and similar designations; nor did they formally distinguish actual grace from sanctifying grace. But, in consequence of modern controversies regarding grace, it has become usual and necessary in theology to draw a sharper distinction between the transient help to act (actual grace) and the permanent state of grace (sanctifying grace). For this reason we adopt this distinction as our principle of division in our exposition of the Catholic doctrine. >
< 1. As we have seen that sanctifying grace designates a grace producing a permanent condition, it follows that it must not be confounded with a particular actual grace nor with a series of actual graces, as some ante-Tridentine theologians seem to have held. >
< Moreover, sanctifying grace as an active reality, and not a merely external relation, must be philosophically either substance or accident. Now, it is certainty not a substance which exists by itself, or apart from the soul, therefore it is a physical accident inhering in the soul, so that the soul becomes the subject in which grace inheres; but such an accident is in metaphysics called quality (qualitas, poiotes) therefore sanctifying grace may be philosophically termed a “permanent, supernatural quality of the soul”, or, as the Roman Catechism (P. II, cap. ii, de bap., n. 50) says “divina qualitas in anima inhaerens”. >
