The main problem with Haring's application of the principle of equity and epikeia on divorced and remarried Catholics is that these 2 principles can only be used for civil and canon laws, not natural or divine positive laws whose author is God himself. One can refer to Fr.Piero Giorgio Marcuzzi S.D.B "The Application of Aequitas Et Epikeia to the Divorced and Remarried" in L'Osservatore Romano for clarification.
I hope our clergy and pastoral workers in China will not be misguided by the well-intentioned but pastorally unsound approach of this article.
