Sunday Mass has been canceled in Sri Lanka this weekend.
Cardinal Malcolm Ranjith made the announcement during a news conference in the Sri Lankan capital on Friday.
He also used the conference to appeal for financial support to rebuild the lives of the victims of the terror attack and to reconstruct the churches targeted.
The Islamic State suicide bombings killed more than 250 people on Sunday and officials are still searching for suspects.
The US Embassy in Sri Lanka has warned people to stay away from places of worship this weekend over concerns about possible further attacks.
On Friday, authorities urged Muslims not to hold congregational prayers over fears that they might be targeted.
However, several mosques did under the protection of security forces.
The decision comes just days after senior priests had shared their fears over security following the bombings.
