Us, a charity that works with Anglican churches across the world, has sent hundreds of friendship bracelets to churches to remind them to pray for women in Zambia who have experienced violence.
Hundreds of women have also sent messages to abuse sufferers in the country.
One woman wrote: "My prayers and thoughts are with you. I know how painful escaping from an abusive relationship can be. Stay the course, and God be with you."
Another wrote: "You are not alone. Many all over the world understand what you are going through and how complicated your life is."
The campaign complements the Anglican Church in Zambia's work to stop violence against women. The Church is working with the Zambian government and others to raise awareness of women's legal rights.
It is also running support groups for women, and providing numeracy and literacy skills so women can be independent.
Grace Mazala Phiri, the national programmes director for the Anglican Church in Zambia, said: "We want women to feel empowered, but we don't want men to feel worthless.
"We have to look at both the victim and the perpetrator to bring about healing."
Rt Rev William Mchombo, the Bishop of Eastern Zambia, said: "The work we do is about showing people they are all equal, that women are valuable and girls are not inferior to boys.
"We're trying to teach the next generation, who will be our future leaders. Part of this re-education involves pushing for women to have a greater role in the Church."
Up to 70% of women in the world experience violence at some point in their lifetime, according to research from the United Nations.
