No, in terms of the authority to officiate as a representative and ordained person of a particularly faith/denomination.
A celebrant does not have these powers conferred on them like a priest. These conferred powers vary from faith group to faith group.
So if you don’t want a full-blown religious service but you do want, say, the words of the committal (when the coffin goes into the grave or the curtains are drawn at a crematorium) to be spoken by a priest in order to give them “full spiritual power”, you are going to need to find a priest to work alongside either you or a celebrant.
Most priests like to run the show completely and will not settle for playing a bit part.
Remember, a religious funeral is not a tailor-made ceremony, it is a universal ritual which can only be personalised up to a point.
Some priests, though, will be quite happy to perform just the religious bits.
Many celebrants have a spiritual presence that permeates everything they do from the first contact with you, throughout the funeral and afterwards.
Some would say these are extraordinary gifts but are not conferred on them by a specific faith group.
