Rev Mike Long, who has been supporting families affected by last June's disaster, also said the sessions were an appropriate way to begin an inquiry into what happened.
The leader of Notting Hill Methodist Church - located a short distance away from the block of flats - told Premier: "Although it's a very long process - these commemorative hearings - because sadly so many people have died, I do think it's very significant and very important, both for the bereaved and for the wider community."
Relatives and friends of the 71 people who died in the fire, which broke out on 14th June 2017, are being invited to pay tribute to their loved ones during the next two weeks.
Concerned that the public inquiry respect the grief experienced by the local community, Rev Long went on to say: "I think it's quite unusual but I think it's very much welcomed.
"I don't know how many families have taken up the invitation to do this but I would like to think this signals something important about the approach of the public inquiry..."
Chaired by retired Court of Appeal judge Sir Martin Moore-Bick (pictured), the public inquiry was announced in response to widespread anger that safety concerns raised by residents of the tower before the fire were not addressed.
The first phase of the inquiry - scheduled to last until late October - will examine the immediate cause of the blaze and how it spread.
The handling of residents' warnings about safety at Grenfell Tower and the response of local and national government to the fire will be examined in the second phase of the probe.
