A Service of Commemoration will be held at St Andrew's Cathedral on Saturday in the wake of the Easter Bombings in Sri Lanka.

More than 250 died and around 500 were injured when suicide bombers targeted churches and hotels on Easter Day. The bombers struck during packed Easter services in the cities of Colombo, Negombo and Batticaloa.

Archbishop Glenn Davies, spoke within hours of the blast, calling for prayer for the survivors and the families of those killed. "Our hearts cry out for our brothers and sisters in Sri Lanka." Dr Davies said. "This senseless slaughter is a tragedy of vast proportion, especially as it was carried out on Easter Day, mocking the day of hope and salvation for so many. May God comfort survivors and those who have lost loved ones."

Members of the public and especially members of the Sri Lankan communities in Sydney are invited to attend the service at 11 am on Saturday.

The service will be addressed by the Dean of Sydney, the Very Reverend Kanishka Raffel, who is of Sri Lankan heritage and will be attended by the State Moderator of the Presbyterian Church, the Reverend Kamal Weerakoon, who was born in Sri Lanka.

"As more details come to light, it is clear that the attacks in Sri Lanka were deeply evil in planning and execution," Dean Kanishka Raffel said.  "Christians are urged in the Bible to 'overcome evil with good'.  In the immediate aftermath of such painful and widespread loss, this means offering compassion and help, weeping with those who weep, seeking God in prayer and refusing vengeance and hatred."

"Easter is God's great demonstration of good overcoming evil. Jesus has been raised from the dead and will bring a new world, where there will be justice for all and every tear wiped away." Dean Raffel said.
