The most likely result is that politicians and teachers will stop going to confession.
A few years ago, our pastor was doing sick calls at a local catholic hospital. One of the individuals he visited was a retired Democrat politician whose son had followed in his footsteps and was well respected. The senior politician had just been delivered a death notice by his medical team. During his pastoral visit, this individual asked the priest to hear his confession.
The priest, ever conscious of the seal of confession, used the situation as an example to uphold the right to life position to his congregation at a Sunday liturgy. While no name was mentioned, it was fairly easy to figure out who had made the confession. The priest did not expound on how he administered the sacrament, he encouraged his parishioners to be pro-active in support of life.
These politicians and teachers have consciences but place politics before faith. Those fortunate enough to reach the point of the above-cited politico, use their final days to draw the 'repentance' card, much like Ted Kennedy. Ultimately, they will stand before God and be judged, like all of us.
