[daniel1212]

Funny, never saw that in a Catholic Church or any services from the Vatican, etc. Perhaps you should send them a note to read scripture? They’re obviously not in the know.

Its obvious that they do not consider themselves bound to no add nor subtract from it.

Hear the voice of my supplications, when I cry unto thee, when I lift up my hands toward thy holy oracle. (Psalms 28:2)

Thus will I bless thee while I live: I will lift up my hands in thy name. (Psalms 63:4)

Lift up your hands in the sanctuary, and bless the Lord. (Psalms 134:2)

Let my prayer be set forth before thee as incense; and the lifting up of my hands as the evening sacrifice. (Psalms 141:2)

That said, i myself do no feel too comfortable doing so.

It could be a social embarrassment factor. Wanting to fit in to the crowd. This isn’t any kind of unforgivable sin, but it omits something that would make the worship more enveloping. It serves as a reminder that later, the right thing to do with those hands is to offer their service to the Lord in any circumstance.
