Ronaldo Baccelli was born in Brazil in 1954. From a young age, he was a disciple of the great Catholic leader Prof. Plinio Corrêa de Oliveira – founder of the Brazilian Society for the Defence of Tradition, Family, and Property (TFP) – from whom he learned to love the Catholic Faith and the principles that govern Christian civilisation. He committed himself to promoting the ideals of the TFP throughout Brazil, Europe and Asia.

In the 1980s, Prof. Plinio Corrêa de Oliveira identified a significant threat to the Church and Christian civilisation resulting from heretical theories circulating in Catholic environments in India.

He then tasked the author with conducting an in-depth study on interreligious ecumenism and compiling documentation with the aim of informing the Holy See and encouraging the general public to respond to these threats.
