This fine Bishop recognizes what so many do not: catholic conscience is not some internal or emotional mechanism.  Our conscience is provided to us by the church.  We have a thousand years of bishops and popes telling us what is right and wrong.  All we need do is consult the catechism for answers to any vexing moral questions, then do as we are told.  If necessary, ask a priest what to do.  Until the laity recognize that its vocation is to obey those selected by God to lead the church there will be continued confusion.  And there is no need for confusion.  The church has set out the law and Jesus taught that we would be saved by obedience to every provision of the law.  We need only stop thinking, start obeying, and like the good sheep, follow the lead of the shepherds.
