The clergy do not wear a head covering while they are at prayer during the Mass.
On the issue of if women should veil themselves or not, most of the objections raised by modern Catholic to having women wear Veils are based on the idea that the new code of canon law issued in 1983 does not reiterate the specific mandate that appeared in the 1917 code of Canon Law, and therefore there is no longer any obligation for them. The 1917 code stated:
Men, in a church or outside a church, while they are assisting at sacred rites, shall be bare-headed, unless the approved mores of the people or peculiar circumstances of things determine otherwise; women, however, shall have a covered head and be modestly dressed especially when they approach the table of the Lord.
The modern Catholic will argue that, Canon 6 of the new 1983 code abrogates the 1917 code, and therefore, any commands given in the 1917 code are not applicable after 1983. Cannon 6 states:
When this Code takes force, the following are abrogated: (1) the Code of Canon Law promulgated in 1917.
Although, the fact is that the 1983 code goes out of its way to accommodate the 1917 code. For example, canon 20 states:
20 A later law abrogates, or derogates from, an earlier law if it states so expressly, is directly contrary to it, or completely reorders the entire matter of the earlier law. A universal law, however, in no way derogates from a particular or special law unless the law expressly provides otherwise.
21 In a case of doubt,(e.g. head coverings for women) the revocation of a pre-existing law is not presumed, but later laws must be related to the earlier ones and, insofar as possible, must be harmonized with them. (Code of Canon Law 20,21)
It seems then, far from disavowing itself from the 1917 code, if the 1983 code is silent on an issue (e.g., as it is with head coverings), it requires that we not presume a previous law was revoked, and, in fact, the 1983 code says it “must be related to” and “must be harmonized with” the 1917 code. Although on a legal basis the 1983 code abrogates the 1917 code, it is clear that the 1983 code imposes a legal stipulation on itself in the way it relates to the 1917 code, a stipulation which requires it to address the 1917 code so that the final decision on a given issue will be in harmony with, not opposed to, the 1917 code. This would be especially applicable in regards to a traditional practice that stretched uninterrupted for over nineteen hundred years and did so because of the original mandate in Holy Writ.
