Rt Revd Christopher Cocksworth, who's also the Bishop of Coventry, said: "The consistent commitment that HRH The Prince of Wales has shown in defending freedom of religion or belief is appreciated deeply across the Churches and Faith Communities both here in the UK and further afield.
"With freedom of religion under such duress around the world, The Prince of Wales's most recent address to Parliamentarians at the launch of the Aid to the Church in Need Report is a profound and inspiring reminder to us all... of the critical importance of working together to defend this most basic of human rights as set out in Article 18 of the Universal Declaration of Human Rights.
"Unless we can find ways of halting and, in time, reversing the rising tide of societal and government restrictions to freedom of religion, it will become even harder to combat the sickening reality of religiously motivated violence that has become all too common in today's fractured world."
Prince Charles made the comments after the charity Aid to the Church in Need released a report saying Christians are the most persecuted religious group in the world, and face oppression in more than 40% of the world's countries.
It also says religious freedom in the world is "in serious decline."
The Prince of Wales said: "The horrendous and heartbreaking events in Iraq and Syria have brought the subject of religious freedom and persecution to the forefront of the world's news.
"It is an indescribable tragedy that Christianity is now under such threat in the Middle East; an area where Christians have lived for 2,000 years, and across which Islam spread in 700AD, with people of different faiths living together peaceably for centuries."
"We have yet to see the full potential of faith communities working together."
