There is no doubt that many people will be inclined to watch the nuptials of the latest Royal Wedding. Some will feel magnetised by the moment, others will be eager to see the habilment. One needs to remember, though, that even clothes will include vestments and the marriage is a formal Xtian marriage in a Church (כנסיה).
Those who may watch the wedding ceremony will do so through their Television or the Internet. Is there any halachic issue?
Rav Moshe Feinstein (Igros Moshe, Yoreh Deah 3:129) stressed that it is not permitted to enter a Church, even if one only intended to admire the architecture or art. In Yoreh Deah (3:77) he goes as far as not permitting the use of Church facilities for a Talmud Torah where that Talmud Torah had difficulty finding accomodation. Mori V’Rabbi, the Rav was asked after the assassination of John F. Kennedy, whether it was permitted to watch the service on the Television. Rav Soloveitchik responded that in the same way that it was forbidden to enter a כנסיה, it was equally forbidden to bring the כנסיה into one’s house. He noted that the clergy at the time encouraged those who were not able to attend, to avail themselves of participation in the service by watching through the Television.
In summary, it is best to spend one’s time on permitted activities, and how much more so, by having a Shiur or learning from a Sefer at that time.
STOP PRESS: I am advised that this Wedding is being held on a day that one is forbidden to watch ANY Television (Melacha). That being said, many will I estimate wish to “catch up” and watch some highlights.
