In 1984, Amaral carried out a year of pastoral ministry in the parish of Ossu, in the then Viqueque District. From 1985 to 1988, he studied theology at the Major Seminary of St. Peter in Ritapiret, Flores, Indonesia.[2]
In 2005–2007, Amaral undertook studies for a licentiate in dogmatic theology at the Pontifical Urban University in Rome. From 2007, he was Professor of Dogmatic Theology and Prefect of Studies at the Major Seminary in Dili. From 2008, he served as Chancellor of the Diocese of Dili and Director of the Diocesan Magazine Seara.[2]
The consecration ceremony was held at the Sanctuary of John Paul II, in Tasitolu, Dili,[5] and the installation took place in Maliana.[6]
In August 2015, Amaral joined with Archbishop Girelli, Bishop Nascimento, 8,000 faithful, and Archbishop Joseph Marino, the new apostolic nuncio to East Timor, in a celebration of 500 years of the Catholic Church's presence in East Timor. The main celebrant was Vatican Secretary of State Cardinal Pietro Parolin.[7]
Three months later, on 26 September 2017, Archbishop Marino, Bishop Nascimento and Amaral all attended the opening of St. Joseph Seminary, the country's second minor seminary, in Amaral's diocese. The new seminary, located within a refurbished building owned by a local diocesan school, was set to begin with 22 students.[9]
On 26 March 2020, Amaral, along with Archbishop Virgílio do Carmo da Silva and Bishop Nascimento, signed a statement confirming a decision of the Timorese Episcopal Conference cancelling mass during Easter in the whole of East Timor, due to the COVID-19 pandemic.[12] In May 2020, the three bishops issued a statement officially reopening churches for Eucharistic celebrations.[13]
In early March 2022, in the lead up to that month's presidential election in East Timor, Amaral, together with Archbishop do Carmo da Silva and Father Alipio Pinto Gusmao, Administrator of the Baucau diocese, sent a pastoral letter to all Catholics stating that politics is a "sacrament",[14] and asserting that:
"All Christians involved in politics should live a political ethos based on the teachings of the Church about how to be a good person in the world and that faith in God should be used to measure politics."[14]
In April 2023, ahead of that year's East Timorese parliamentary election on 21 May, Amaral called upon politicians to "take a role in maintaining peace and stability" rather than "attack each other or spread hatred in the presence of supporters."[15]
Personal life
At the end of February 2022, Amaral underwent intensive treatment at Guido Valadares National Hospital (HNGV) in Dili for hypertension.[16] In March 2022, he flew to Malaysia for further medical treatment.[17] He returned the following month.[16]
