Ok. So the priests decides if an attempt was made, not the penitent.
Even tho we, penitents, think, when we go into the confessional - kneel down - and confess (even things that may not be sins) are under the seal. If the priest says there was no attempt, then there was none.
Nope.
You are making presumptions.
He (I am assuming this is a teenager or not much older than that) appears to be royally peeved at being forced to go (either to church, or to confession, or both). He goes into the confessional with an attitude as wide as a Mack truck. Anyone who is paying attention could tell he was under full steam.
He walks into the confessional (and I would lay odds his parent was outside - either in the church or in the parking lot), and he starts to vent. His attitude, as exhibited by his body posture, his motions, his tone of voice, the look on his face - all add up to someone who has no intent on his own to be there. He is being coerced, he knows it, and he is going to let you know it.
That is not a penitent. That is a kid who wants nothing to do with church, or confession, or a sacrament, or reconciliation.
And the priest calls a spade a spade.
That has nothing to do with “we, penitents, think, when we go into the confessional - kneel down - and confess (even things that may not be sins) are under the seal”. Your example is people going in who intend to confess.
The kid didn’t intend; the priest got the message, and stopped the charade.
Someone intending to confess is going to give indications that is what they are there for. The priest was there; he made the call.
The OP was under the impression that the seal attaches if you go in. Almost always, it does, because almost always, the person going in intends to start the sacrament of reconciliation. In this circumstance, the individual did not intend to do so; the priest made the call, and that is that. It is an esoteric area in that it is rare (most people going in intend to confess). While there is a presumption that anyone entering intends to confess, it is not absolute.
And if you don’t intend to confess, to start the sacrament, then it does not start, and the seal does not attach.
So it is not correct to say that one intends and the priest over-rules the intent (that is the implication of your comment).
It would be clearer to not use the word “penitent” for absolutely anyone who enters the confessional, as the implication of the word is that one is intending to confess. By its definition, a penitent is one who intends to confess. What we are dealing with in this thread is one who does not intend to do so, and is thus not a penitent.
Anyone entering the confessional is going to have the presumption they are there to confess, but that presumption can be overcome by evidence to the contrary. The kid gave the evidence, and the priest made the decision. It was not random, or willy-nilly, or subjective. It was based on objective, observable evidence, including, but not limited to what the kid said.
