Genuflection1341. Why do Catholics genuflect before entering the seats?
They do so to Christ personally present in the Holy Eucharist. When Christ allowed St. Thomas the Apostle to touch the wounds in His hands and feet, St. Thomas said, "My Lord and my God." The same Christ left Himself present in the Eucharist when He said, "This is My Body," and when Catholics come into His presence they offer Him the tribute of their deep reverence and worship by genuflection. You, too, would kneel before Christ, if you believed as Catholics do.
Sign of the Cross1342. I was rather amused by noticing how Catholics superstitiously cross themselves before beginning their prayers.
A professing Christian laughing at fellow Christians for making the sign of the cross is an anomaly! It shows how far Protestantism has drifted from the spirit of true Christianity. Catholics at least say with St. Paul, "God forbid that I should glory save in the cross of our Lord Jesus Christ." Gal 6:14. The early Christians made very much of the sign of the cross, even as Catholics do today. Tertullian, who died about 240 A.D., wrote, "In all our travels, in our coming in and going out, in putting on our clothes and our shoes, at table, in going to rest, whatever employment occupies us, we mark our forehead with the sign of the cross." St. Ephrem, who died in 373 A.D., wrote, "My son, mark all your actions with the sign of the life-giving cross. Do not go out from the door of your house till you have signed yourself with the cross. Do not neglect that sign whether in eating or drinking or going to sleep, or in the home or going on a journey. There is no habit to be compared with it. Let it be a protecting wall round all your conduct, and teach it to your children that they may earnestly learn the custom." An early Christian would certainly be at home amongst Catholics, but like a fish out of water amongst Protestants.
