Yes, it says that every knee shall bend at His second coming. But, it doesn't say that every knee won't bend before His second coming. Other than saying that every knee shall bend at the name of Jesus (His name occurs in the Catholic Mass several times), the NT doesn't say that one shouldn't kneel or genuflect in His presence.
When the Blessed Sacrament is exposed in a monstrance, the traditional rubric is to kneel in the aisle before entering the pew. When the Blessed Sacrament is reserved in the tabernacle, the custom is to genuflect before entering the aisle.
As I mentioned before, kneeling and genuflection are signs of respect as well as acts of humility (for example, one's defenses are down when one is kneeling).
Oops, "before entering the aisle" should read "before entering the pew"
No, but the Church did at the First Ecumenical Council, and only on Sundays, precisely because everyone was making up their own rules.
Some habits die hard I see. Certainly there was no mention of sitting in the Church either.
Making up rules as one goes along and ignoring Ecmenical Councils is what caused the corruption and split. The same thing happened in the 16th century when Christianity splintered one more time over what appearted to have been man-made rules.
