Taking up issue of kissing a bishop’s ring, which we have look at before, this is from a reader:
I wanted to add a few comments about kissing a bishop’s ring outside of the liturgy.
Technically there is no hard fast rule about genuflecting on the left knee, though this is often a pious custom. During the liturgical actions, the genuflection to a prelate is always made on the right knee, because he has the fullness of Christ and is Christ at the altar.
Also, one should only bow low to an auxiliary bishop when kissing his ring, because he is not the local ordinary.
The confusing point about this is that traditionalists were so accustomed to genuflecting to Archbishop Lefebvre (who because of his personal rank one would genuflect to), that they continued the practice unaware with the four new bishops consecrated for the SSPX, who are actually only auxiliary bishops themselves. Several SSPX priests attempted to correct this less-correct practice early on, but gave up after some time. In any case, my 2 cents worth
Genuflecting on the left knee for a bishop: Yes, pious custom. But it is a good one. If one forgets and does so with his right knee, he won’t got to hell for it.
In liturgical actions, the genuflection is always on the right knee. Good reminder!
One should bow, not genuflect, to an auxiliary. Okay, he is not the ordinary. Though I think one should always genuflect in the case of a Cardinal, anywhere, and probably a papal legate.
The "personal rank" of the late Archbishop Lefebvre and genuflecting: He wasn’t an ordinary anymore. Why genuflect?
The four bishops consecrated by Archbishop Lefebvre are NOT auxiliary bishops. They are not in union with the Holy See and therefore have no mandate which would indicate a genuflection. However, I believe they often take to themselves trappings they would have had no right to use even in the old days. Let’s us pray that their situation, and excommunications, can be taken care of soon, so that everything can be regularized.
