It certainly is true that little church effort is made to persuade Catholics to obey the church's ban on contraceptives. That effort failed dismally in the 1970s. Many priests disagree with the ban and are embarrassed to urge Catholics to follow it.
Catholics reject it out of hand.
But the conventional wisdom that the bishops have given up this fight is flawed. Frequently, language is fuzzy. Cardinal John O'Connor of New York City, then chairman of the bishops' Pro-Life Activities Committee, demonstrated this latter approach in his archdiocesan newspaper in June 1990. The question is one of the means used. The church does not accept the use of artificial means.
