In her home country, women carry out various pastoral tasks such as visiting the sick, religious instruction or catechesis and lead church movements or are members of parish and pastoral councils, said the nun when asked by katholisch.de.
Female religious congregations are also involved in education and healthcare, especially in rural areas and for the poor.
"They are the hands of the Church, they are also its eyes and feet," emphasised Randrianirina. She wants to bring the enthusiasm of these women from Madagascar, "who love the Church and long for its well-being", to the Synod on Synodality in Rome.
The church in Madagascar is a young church overall and has only existed in its current form since the 19th century.
"It is also young because most Christians are young," said the nun.
From the very beginning, lay people have been involved in the introduction of the faith in Madagascar alongside priests and religious and have ensured the survival of the church.
"The Church in Madagascar today does not forget how important this collaboration and participation of the various groups of people is, because it attaches great importance to the fact that lay people and consecrated persons are represented in the pastoral councils of the diocese and in the parish councils."
She also wants to bring this spirit of cooperation to the Synod on Synodality as a contribution from Madagascar.
"Thanks to baptism and in the name of love for God, everyone participates in the life of the Church according to their gifts, talents and vocation. Even if I have to admit that this participation is not always easy."
A fruit of the Holy Spirit
For Randrianirina, synodality has already had a practical impact on the church in Madagascar.
After the first session of the Synod on Synodality last year, there had been meetings between bishops, male and female religious superiors and secular institutes - for the first time in the history of the country's church.
"We spent two days together listening to each other and engaging in dialogue to discern how we can improve relations between us and how we can better fulfil the mission of the Church entrusted to us," explained the nun. This is already a fruit of the Holy Spirit.
For the Synod on Synodality, she hoped, in line with the prayer for the Synod, "that we learn to walk together so that ignorance does not lead us down the wrong path and partiality does not influence our actions," said Randrianirina.
"I hope that the Church can fulfil the will of God."
The nun is taking part in the Synod as a non-episcopal delegate for Africa.
She is one of the first women to have the right to vote at a synod of bishops.
Around 27 per cent of Madagascar's population is Catholic.
This means that a total of around 4.7 million Catholics live on the island.
