Again, this is a personal decision as to whether a minister or celebrant officiates at the funeral service. A celebrant is someone who takes the funeral service, generally without a lot of prayers or bible readings and can provide either a faith or non-faith-based service as decided by the family.
If you would like a minister to take to the funeral but haven’t been to church for a while, don’t be concerned. Ministers are happy to officiate at funerals outside of the church either at the graveside or a chapel.
