When Mount Zion Church opened in 1888, the North British Daily Mail reported:

QUARRIERS SAY:
The building needs £500,000 of repairs over the next 10 years.
FACT: Quarriers has only spent on average £4,000 per year in recent years.
Despite this, an independent structural survey has shown the building is in good condition and only requires routine maintenance.
QUARRIERS SAY:
The charity can't afford the upkeep of the church.
FACT: Mount Zion is eligible for help from a new Heritage Lottery Fund (Repair Grants for Places of Worship). Churches in Paisley and Greenock have already received substantial sums.
QUARRIERS SAY:
They are pressing ahead with their plan to sell up to a developer.
FACT: Historic Scotland has given the church a Category B listing because of the building’s history and architectural features. We presented a detailed business plan to Quarriers’ management showing a variety of ways in which the church could generate income so it would not be a financial burden on the charity.
