Ted Kennedy Jr. shared a touching testimony of his father Sen. Edward Ted Kennedy during a funeral service at a Roman Catholic Basilica in Boston Saturday following his death last Tuesday at age 77 following a battle with cancer.

The senator's son said he would never forget the words his father told him at a young age after he was diagnosed with bone cancer and was getting used to walking with an artificial leg. Ted Jr. recalled an anecdote of a winter day when he fell trying to climb a hill using the artificial leg.

I said, I can't do this. I said I'll never be able to climb up that hill, Ted Jr. recalled in the mass. Then tearfully he remembered the words of his father, He said to me. I know you can do it. There is nothing that you can't do. We are going to climb that hill together even if it takes us all day.

He says they got to the top of the hill that time.

Friends, relatives, political co-workers and President Barack Obama attended the funeral mass in our Lady of Perpetual Help basilica in Boston.

Senator Ted Kennedy was one of the most influential senators in the history of the U.S. Obama, in a eulogy, called him the soul of the Democratic Party and the lion of the U.S. Senate and praised him for being a voice for the poor and powerless of the country.

The Senator's body will be laid to rest in Arlington National Cemetery, the Associated Press said.
