Father-of-two David Charmbury was assaulted when he was opening up the Church of Latter Day Saints in Chelmsley Wood, Birmingham, on August 16.
The 45-year-old, who now serves as a Mormon bishop in Birmingham, is believed to have suffered the head injuries when he tried to prevent his car being stolen.
Following the assault he was taken to Queen Elizabeth Hospital where he was put into an induced coma.
A spokesman for West Midlands Police said: "Mr Charmbury is continuing to improve, is out of intensive care and is in a stable condition."
Mr Charmbury, a surveyor, was influential in Telford's Southwater project and is a bishop in the Mormon church. He was previously a reverend at The Church of Jesus Christ of Latter Day Saints in Wellington, before moving to Birmingham.
He played a key role in Telford's £250 million Southwater development, as well as the ongoing Lawley Village project. He worked as a development surveyor at Telford & Wrekin Council from 1992 for about nine years.
Mr Charmbury was a student at Meole Brace School and then attended Shrewsbury Sixth Form College.
Harley Heyes, 36, from Chelmsley Wood, was arrested in connection with the offence and has been charged with assault causing grievous bodily harm with intent, taking a vehicle by force and having no insurance.
