Just a few days ago, more than 10,000 walkers gathered in Washington DC to take part in the third annual "America Supports You" Freedom Walk.
"Being here is my Christian duty and my civic duty," Gloria Chance, a Department of Agriculture employee, told American Forces Press Service.
Although Chance said she doesn't often attend Sunday morning church services, she considered the Freedom Walk a worthy exception, according to AFPS.
"It's so important that we as a country embrace the freedoms we have and recognise that September 11 was a direct assault against all of us," she said. "We need to remember that so it doesn't ever happen again - because when you forget the past, that's when it comes right back at you."
The spirit of unity that pervaded across ceremonies Tuesday also spanned across faith lines.
One pastor in Alabama said that the events of the tragedy had raised America's "God-consciousness".
Not only did more people turn to prayer, said Chris Toole, pastor of SouthPoint Church, in a Eufaula Tribune report, but it forced the church to re-examine their ministry and their church which had become ingrown.
"It made us open our eyes to people of different faiths," said Toole.
In Sacramento, one college student who was a scheduled speaker for the Interfaith Worship Service hosted at the Cathedral of the Blessed Sacrament said the event made her more religious.
Ruben Arocan, contemplating the priesthood, told the Sacramento Bee, "It brought me closer to God but also to the reality that we live in a harsh world. With God in our life, we can always get through that."
This year's anniversary date was the first time September 11 fell on a Tuesday, the same day the 2001 attacks actually occurred. Fatalities from the series of events totalled 2,974. Flags were to return to full-staff on Wednesday.
