If you have symptoms that indicate a severe medical problem, would you just ignore them or find out the cause and treat it? If you find your car veering in one direction when you drive do you just compensate by turning the steering wheel in the opposite direction, or do you determine what the problem is and fix it? If you are in charge of a once vibrant organization and find that a great number of your members are not attending meetings, not participating in the programs, not paying their dues, not even paying attention to what the leaders of the organization are saying, but still consider themselves members, would you not want to know the extent of the problem and why it is happening?
I am not saying that the Church must change to fit the views of all those who have negative views, but the Church MUST ask itself what is going on and why, so you can do something about it. Its mission is not to weed out the marginal or the imperfect, but to bring them in to the faith. To me, that would follow the words and deeds of Jesus.
Our diocese is apparently emphasizing evangelization this year. Parishes are supposed to start a program. My first recommendation for our parish is to contact people who are no longer participating, including all the young people who have been catechized and confirmed but never return, and the adults who bring their children in for baptism and first communion and appear to be strangers the rest of time, and those who were participating parish members but left. Not to evangelize them, but to ask them WHY? Only then can the Church hope to do anything to get them back or to make them full participants again.
I would rather do that FIRST before trying to convert Baptists, Lutherans, and Methodists.
