He's a good confessor.
Actually, he's a very good priest. I especially love a priest who loves the Sacrament of Penance. Father can rightly claim good success for his blog because he has used it to encourage so many to go to confession - and it appears not a few have, some after many years of being away. I've known priests who were not that dedicated to confession. I've known priests who weren't especially good confessors. Fr. Z is both dedicated and good.
Today he has another very good post on confession. It's very encouraging, especially for anyone who struggles with habitual sin or addiction.
Finally, don’t be discouraged. God works wondrous things through fragile and erring priests: you obtained absolution for your sins! Now, be of good cheer. Even though you have a long road ahead, you are pointed in the right direction. - Read the post here.As St. John of the Cross once said: "[T]he holier the confessor, the gentler he is, and the less he is scandalized at other people's faults, because he understands man's weak condition better."
