Firefighter Glen Thorman, 54, said the motion-activated device took two pictures of the winged being at his residence in East Jordan, Michigan.
He said: “I have a security camera that sits in my window and I have it set to take two pictures, back to back, a second or two apart.
“I had it going off after midnight that night and I didn’t check it then, but when I was eating lunch the next day I was thinking, ‘oh look, the camera took a couple of pictures last night’.
“I was like, ‘whoa, it’s an angel’. I mean, honestly, tears started coming from my eyes and right then I sent it to my wife and I sent it to my pastor.
“The pastor said right back, ‘that’s an angel’.”
The first picture shows a winged creature in the air and the second shows it flying off.
Glen continued: “As a family we pray for God to send angels to protect us and watch over us, and when that happened it just blew me away.
“I have a really strong faith in God as it is, but it was just like one more thing added to it.
“It strengthened our faith and confirmed, ‘this is real, God is real, angels are real and miracles happen’.”
Some sceptics have suggested that the camera in fact captured a moth flying close to the lens.
But the faithful of East Jordan insist that it was too cold for moths and – if it were an insect – then the camera would have taken similar photos before.
Mr Thorman added: “My camera takes a lot of pictures but I’ve never had anything like this.
“As a family we pray for God to send angels to protect us and watch over us, and when that happened it just blew me away”
“It’s been there a long time, but it’s never taken any pictures of any moths or been set off by one.
“We still had snow on the ground, so it was still cold, so I don’t know that there were any moths out.”
He went on: “Lots of people are talking about it here, texting me and messaging me, saying that it’s a miracle and it’s beautiful, and praise God.
“There’s always sceptics and they say ‘that’s a moth, you guys don’t know what you’re talking about’.
“And I just respond saying everybody is entitled to their opinion and our opinion is: that’s an angel.”
Deneille Moes, senior pastor at Jordan’s River Church where Mr Thorman and his family worship, had no doubt that the photo showed an angel.
She said: “Of all the photos Glen has ever been sent by his security camera, there has never been a bug or moth recorded.
“The issue with the moth theory is it was just too cold. It’s been a horrendous spring.
“We just got four feet of snow, and at the Thorman residence it’s much colder than where we are – they live out in the boonies.
“Northern Michigan is cold. It takes awhile for us to warm up. Moths just don’t appear until the weather is warmer.”
She added: “I believe the image is of an angel.
“We do believe that God sends angels to keep us from harm when we pray.”
