This is a gesture of opening oneself up to receiving the word of God during the Our Father.
The church was concentrating on community building, hence the holding of hands to indicate 'one community'.
New leanings are to the outstretched hands in open reception of God the Father during the Our Father; it is going back to being a very individual thing, but also does have that community and openness aspect with the outstretched hands.
I kind of lean toward saying the words of the consecration with the priest. What do you think? If I start it will it catch on?
