Before Vatican II only males could serve at Mass. Now females are permitted to serve at Mass as well as males. Did the Code of Canon Law only allow males to serve, and now it has been changed? Or were females always allowed to serve at Mass?
Answer by Rev. Mark J. Gantley, JCL on 10/28/2008:
When the 1983 Code of Canon Law was promulgated, it no longer restricted serving in those liturgical ministries to males. After the promulgation of the code, there was an official clarification from the Vatican making it clear that the law had changed.
Under the 1917 code, females were not permitted to serve."
