you people have to construct false choices to back up your pharisaical spirit. NO ONE HERE is saying confirm anyone in their sin. The example given was clearly a repentant person.
I just read the beginning of the article, but if a remarried person remains in a second marriage, and his original marriage was valid, and he is not living as brother and sister, then there is no objective evidence of repentance.
Now, individual cases can get very complicated, as in cases of conversion, where someone remarries for a second time in good conscience, before coming to understand the objective sinfulness of the second marriage. These cases represent pastoral gordian knots, especially with children involved.
