A vicar faces an official complaint for installing a childrens' plastic table and chairs in a 12th century church.
Rector Lynda Klimas introduced the pint-sized white furniture set as a way to keep young children entertained during services.
But a disgruntled churchgoer has made an official complaint as he feels it has no place in the "historically sensitive and sacred" Lady Chapel.
The matter will now be investigated and, if taken to a tribunal, Rev Kilmas could be given a "lifelong prohibition from exercising any ministerial functions".
Kevin Sims, 67, who has been attending the St Mary the Virgin Church for 20 years, said: "I definitely do not feel the number of children warrants it. My main issues are for aesthetic reasons and reasons of demand.
"There are procedures in place that anyone who makes changes in church has to go through.
"My concern is that if nothing is done it means effectively anyone could change anything."
He has now placed a formal complaint of misconduct against the Rector Lynda Klimas who was responsible for the interior alteration.
But despite Mr Sims stating he knows of "at least four" other parishioners who agree with him, other members of the congregation have welcomed the child-friendly space.
A fellow churchgoer said: "I have never heard so much ridiculous fuss about a tiny little table and chairs. It's lovely to see young children welcomed into the church and given a place to sit quietly and play."
According to church guidelines, priests wishing to making alterations like the introduction of furniture must apply to the the faculty jurisdiction.
Once they have been presented with all the details about what the changes would involve, the local Chancellor then makes a final decision on whether it can be made.
In this instance Mr Sims feels bosses have been misled and given false information about the furniture placed in St Mary the Virgin Church, Maulden, Beds.
For example, he says a report filed to them said the furniture would be "in keeping" with its surroundings - which he highlights it clearly is not.
He also says the rector referred to it as a "children's area" despite clear signage indicating it is the 'Lady Chapel'.
Mr Sims said: "For the Rector to state that this sacred space in church is not a chapel beggars belief and is manifestly untrue.
"My main concern isn't with the furniture itself, although I did highlight I don't think it is keeping and there aren't enough children for it.
"This process relies on being truthful in what they are doing."
The bishop of the diocese must now decide whether or not to confront the rector who brought the children's seating area.
If this happens she could receive punishment from a rebuke to removal from her position.
Kevin added: "I hope the Church authorities now wake up to the seriousness of what has taken place here and that appropriate disciplinary penalties and public censure will swiftly follow."
The Rev Klimas, who was made an honorary Canon because of her contribution to the Church of England, said she was forbidden to comment about the grievance.
Arun Kataria, spokesman for the diocese of St Albans, said: "The complaint will be heard in accordance with standard procedure and will be confidential until the matter is concluded."
