Nick, who is the youngest of Al's three children, is "somewhere on the (autism) spectrum and maybe obsessive-compulsive," the TV star previously told Guideposts magazine.

He added: "But those labels can be frustrating; they don't begin to describe who Nick really is."

Al admitted that St. James has become an important place for Nick to carve out an identity.

Al praised his son on Instagram

"On Sundays when I was feeling really down about Nick — wondering where our son would find his place in this world — I found it a comfort to note that some of the acolytes also had special needs,'' he added.

"One performed his duties in a wheelchair; another had Down syndrome. Nick watched and wanted to join them. And the folks who oversaw the acolytes were happy to have him."

Al - who recently underwent surgery for prostate cancer - has three children. Courtney is from his first marriage and Leila and Nick are with his wife, Deborah Roberts. He often shares videos with Nick, much to the delight of his followers.
