From Catholic Online:
The new version, reflecting the bishops' recent response to the scandal of clergy sexual abuse of minors, says explicitly for the first time that no
seminary applicant is to be accepted if he has been involved in sexual abuse of
minors.
It also incorporates stricter norms, adopted by the bishops in 1999, on
evaluating an application for seminary admission from someone who previously
left or was dismissed from a seminary or a formation program for religious life.
