Then 'splain this one for me:
2Th 2:7 For the mystery of lawlessness is already at work; only he who now restrains will do so until he is taken out of the way. 2Th 2:8 Then that lawless one will be revealed whom the Lord will slay with the breath of His mouth and bring to an end by the appearance of His coming;
Here we see the Church as the proper authority to which individuals may appeal where differences arise.
Don't think I do not respect Apostolic authority or a church's authority. This is not the case. If it were, then how could I quote from their writings? The point is, if their writings are secondary to oral succession, then why even have the writings? If this is the case, then why do y'all quote these writings? What authority do you have to defend your Church. The debate for all Catholics should end with, "because they say so".
It is interesting that you post scriptures indicating that the laity have the ability and even the duty to interpret scripture and identify sin on their own. The question here is that what to do when the church is in sin or teaching errors.
Adiaireton8 is advocating a course of action, namely prayer for the reconciliation of the person who has been excommunicated. This is an act of love, correct? This is also entirely consistent with St. Paul's example after he directs the community at Corinth to excommunicate a son and his mother or stepmother for incest (1 Cor 5: 1,2), he nonetheless admonishes the church to act with charity toward these two individuals. (2 Cor 2:5-11)
1Co 5:5 I have decided to deliver such a one to Satan for the destruction of his flesh, so that his spirit may be saved in the day of the Lord Jesus.
The result of the first controversy you post is that Paul decides to give the offender the death penalty since, because he cannot stop sinning, it is better for him to be dead and hope to be judged well at the resurrection. Does this, perhaps, give us an insight as to what the first Bishop of Rome would have done to these pedophile priests and their leaders who covered for them?
2Co 2:6 Sufficient for such a one is this punishment which was inflicted by the majority,
Again, the majority of the laity decided what was sin (interpreted scripture on their own) and took care of the matter. This does not say, "You should not have interpreted scripture on your own, you're busted when I get there". It says, "good job for taking care of business".
