The group will include the provost and three other members, including city manager David Haas.
Rev Peter Donald, Crown Church, commented: "The working group is purely a council group, and doesn't involve the church.
"I just offer the comment that while I think the council is fully entitled to proceed down this line, it is the prerogative of the church to pray for those in government and to invite the secular authority into the church.
"The church must be very careful about selling out theologically to an approach that loses the Christian distinctiveness of what we do."
Presbytery clerk Rev Alastair Younger, St Columba High, remarked: "It seems there's quite a delicate issue with regard to the kirking of the council.
"By its very name and history it has been the prerogative of the established church to invite political representatives of the community to attend the kirking."
Mr Younger recalled that when he had come to Inverness 31 years previously, he had been invited to a meeting in the town house by the incumbent provost, who assured him there was a mutuality between the church and the local authority.
"In my view," he added, "the prerogative lies with the church and no-one else. The structure of this service is a matter for the church and the content of this service is a matter for the church.
"The matter of ecumenism may well be incorporated into proceedings if it's seen to be seemly by the church, but the idea that we might have a minister, an atheist or whatever in the pulpit gives us a wee problem.
"Ministers or elders could be called to account if a service is outside the parameters of what's considered normal.
"We have to be very careful here. While we may be willing to listen to others, the church is responsible for worship, the structure of that worship and the invitations to attend such a ceremony."
