Guess I will take a
slight exception to this. All sacraments have two constituents - form, and matter. To be a valid sacrament, both form and matter must be correct and present. The sacrament must be performed by the regular or extraordinary minister of the sacrament to be valid
Baptism is an easy one:
Ordinary minister: Deacon, priest, bishop
Extraordinary minister: anyone who intends what the Church intendeds by the sacrament - namely, baptism.
Matter: is an unbaptized person and water
Form: pouring the water over the person, the words “I baptize you in the name of the Father, the Son and the Holy Spirit”.
For the Sacrament of Reconciliation:
Ordinary minister: Priest or Bishop
Extraordinary minister: none
Matter: Three elements from the penitent
- Contrition, with a firm purpose of amendment
- an Integral, vocal confession of sins - see thread, above, where I talk about this
- Satisfaction - performing the penance Father gives you
Form: The hearing of the confession, and the words “I absolve you of your sins in the name of the Father and the Son and the Holy Spirit”
So, yes, it is certainly possible (and common) for Father to ask questions to get at the root of contrition, a firm purpose of amendment, and the integrality of the confession.
For instance, if you confessed, “I am living with my girlfriend”, you might expect father to ask if you are still living with her. If the answer is yes, Father cannot in general grant absolution, because you have committed a sin that admits of serious matter (breaking the 6th and possibly the 9th commandment), you now have knowledge that is a serious sin (Father will surely tell you it is, if you didn’t know before) and you intend to keep commiting it in full knowledge of this - all three elements of a mortal sin are present. No contrition, no firm purpose of amendment, Father
cannot give you absolution, in general terms.
So, depending on the confession and details given, Father may ask questions, and may deny absolution based on your answers.
This is, of course, not a happy circumstance, and all priests will try to help you and counsel you to get into a situation where absolution is possible. No priest likes denying a sacrament to anybody - bringing sacraments to Christ’s Body the Church is after all his life’s work. But pronouncing the words of absolution over someone where valid matter does not exist (and so no sacrament conveyed) is equally terrible.
