Wala daw po sa liturgy ang paghahawak ng kamay kapag dinarasal ang "Ama Namin"?

It is not a norm to hold hands when singing the Lord's Prayer and neither it is necessary. Some do it to express their unity in prayer. However unity is not diminished if you don't. The raising of hands individually may find its origin from imitating the priest who raises his hands during the Lord's Prayer. It further evolved into holding each others' raised hands. It is proper for the priest to raise his hands because as the presider, he gathers the prayers of the people.
