The article is referring to students in Catholic Colleges, as opposed to Catholic students in College. Their survey results indicate that more than half of students on Catholic College campuses did not grow in their faith, or even decreased in faith.
It would seem that the students are either not being formed properly in the faith, or otherwise they are coming in with no religious background in the first place. That half of the students identified as "sacramentally active" said abortion should be legal is quite a surprise to me. The numbers on morality weren't much better either. I never realized that the rates of premarital sex on Catholic campuses were as high as they seem to be. I might not have even guessed they were that high in secular schools. I am probably just naive.
About 64 percent of both Catholic groupings said they agreed that the fullness of God’s truth is found in the Catholic Church. Slightly more respondents, 67 percent of current Catholics and 69 percent of sacramentally-active Catholics, agreed that the communion bread and wine at Mass truly become the Body and Blood of Jesus Christ.
In both groups, 61 percent agreed that women should be allowed to be ordained as Catholic priests.
Among all students at Catholic universities, 60 percent agreed that abortion should be legal, including about half of the Catholics. Similarly, 60 percent agreed that premarital sex “with someone you really care about” is not a sin, including slightly more than half of both Catholic groupings.
Further, 78 percent of all students disagreed that using a condom to prevent pregnancy is a serious sin, including 73 percent of current Catholics and 69 percent of the sacramentally active. Overall, about 57 percent agreed that same-sex marriage should be legal, including slightly more than half of current Catholics and slightly less than half of those sacramentally-active in college.
There is hope in the last line, though:
The survey also found that those who were sacramentally-active, prayed frequently or did not regularly view pornography received higher grades.It's a big picture thing. It is all interconnected. If you make sacrifices in the spiritual life, you are likely to make sacrifices in the secular life as well.
