He said his father “persevered through pain” following the death of Daniel, who collapsed and died suddenly when he was 15 from the genetic heart condition hypertrophic cardiomyopathy.
Yorath was also player-coach of Bradford in 1985 and was at Valley Parade when a fire killed 56 people.
“Football was his lifeblood,” said Jordan, noting that after the Bradford fire, Yorath attended the funerals of all those who died.
Presenter and comedian Elis James delivered a eulogy, saying that Daniel’s death “devastated the whole family and the whole community”, coming seven years after the “horror” of Bradford.
Yorath was “ravaged by grief” for the rest of his life, James said, adding that despite this “wherever he went he left people feeling better… he had time for everyone”.
James added that the hope was that after Yorath’s final breath, “what he heard was ‘Hello Dad'”.
Speaking after the service, James said it was an “honour” to have read a eulogy to Yorath.
“His Wales team of the 80s and 90s is what made me fall in love with football,” James told the BBC.
“He was part of every big moment in Welsh football between the 70s and the 90s, either as captain or manager.
“For me, he’s on the Mount Rushmore of Welsh football.”
Footballer-turned-pundit Chris Kamara described it as a “beautiful service”.
“Terry – what a marvellous career. He did everything and he suffered as well – the Bradford fire and his son Daniel. What a man,” he said.
Liverpool legend Ian Rush paid tribute to Yorath for the huge influence he had on his career.
“He gave me all the confidence,” Rush told BBC outside the church.
“As a manager he always put players before himself and he was something special.”
Rush said he would “never forget” the day in 1991 when he scored the winning goal when Wales beat Germany 1-0.
“It was with the help of Terry making me feel confident and that’s something I’ll never forget,” he added.
