A member of Pope Francis' Council of Cardinal Advisers has warned that anti-Muslim rhetoric from the US Republican Party presidential candidate could stir up division.
In an interview with Irish broadcaster RTÉ News, Cardinal Seán O’Malley, Archbishop of Boston in the US, said: "It’s very easy to stir up resentment and to blame groups of people.
"I think immigration is such an important issue, requires a lot of reflection. It requires people with wisdom to come together and talk about what is best for the common good."
He continued: "All of us need just immigration laws and a way of dealing with immigration that will not dehumanise people".
The cardinal was speaking during a trip to Ireland for the re-dedication of the basilica of Our Lady of Knock after a €9m refurbishment.
He also said he was worried that the recent terrorist attack in France could lead to scapegoating Muslims.
He urged Catholics to heed the advice of Pope Francis to strengthen dialogue with Muslims.
Republican Donald Trump last week chose Evangelical Christian Mike Pence as his vice-presidential running mate. During his campaign, Trump has been criticised for inflammatory remarks, including comments suggesting Muslims should be banned from entering America.
