Lord Ahmad of Wimbledon, who was appointed in July as the Prime Minister's special envoy on Freedom of Religion or Belief, also praised those who stand up for the right to exercise faith freely.
He said: "I am committed and I shall continue to push for a world where people of all faiths and none can live their lives free of discrimination, free of fear, free of persecution."
In a video released by the Foreign & Commonwealth Office - where he serves as a minister of state - Lord Ahmad said it was right to remember those "who have suffered and continue to suffer" for their faith.
He added: "We salute those who stand courageously for these rights, who promote tolerance and respect between communities, different faiths and religions."

It is estimated 75-per-cent of the world's population live in countries where freedom of faith is not guaranteed.
Christian Solidarity Worldwide (CSW), a charity which highlights incidents of religiously-motivated persecution around the world, encouraged Christians to pray about the issue.

Chief executive, Mervyn Thomas told Premier: "It's a huge issue in the world. So, it's very important that we have a day that remembers that, to raise awareness but, more importantly... make a difference to people.
"Prayer is the number one action that people can take. We always talk at CSW about prayer and protest together. The two of them can make a big difference."
