I emailed Gateways and was told its not assur. I pushed it further and asked them to pose the question to Rabbi Becher and he said “It is not a specifically christian custom. Also the fact that he is not going down on both knees means he is not imitating kneeling in Church. However, I would not recommend it as it does have an odor of a gentile practice about it.”
What do you say?
