According to a press release to which Prensa Latina had access, Marichal developed an ecumenical vocation of total dedication and honesty.
He held different positions in religious organizations such as the Student Christian Movement, the Caribbean Christian Conference and the Council of Churches of Cuba.
He was the president of the latter from 1996 to 2000, a period in which he carried out countless actions for the return of the child Elian Gonzalez to Cuba.
In 1999, the religious leader organized the First Cuban Evangelical Celebration with the motto Love, Peace, Unity.
At the same time, he taught several generations of students, as a professor at the Evangelical Seminary of Matanzas and served as the first coordinator of the Cuban Interreligious Platform. He was also a promoter of dialogue among all religions on the basis of respect for diversity.
From this project, he promoted concrete activities for the return to their families and people of the five Cuban anti-terrorist fighters imprisoned in the United States since 1998, with total consistency between his religious faith and his revolutionary commitment.
He was also a deputy to the National Assembly of People’s Power from 1998 to the present legislature in the International Relations Commission.
