The Catholic Herald criticised Sosa for being one of over 1,000 signatories of a 1989 letter welcoming Cuban dictator
Fidel Castro to Venezuela in 1989, Castro having repressed the
Catholic Church in Cuba during his time in power. George Neumayr of the conservative
American Spectator described Sosa as a "Marxist", "a Venezuelan communist, and modernist". In February 2017, in response to
Cardinal Müller's argument that permitting the reception of
Communion by the remarried contradicts Jesus's words in the Bible that marriage is indissoluble and Müller's insistence that those words are unchangeable, Sosa argued for a "reflection on what Jesus really said", and described the Gospel as "relative", being "written by human beings" and "accepted by [...] human beings". Sosa also argued that the doctrine of the Church is in "continuous development", and "never in white and black". Sosa's remarks drew criticism in the Italian media. The English priest and consulting editor of
The Catholic Herald Alexander Lucie-Smith disagreed with Sosa, arguing that the Church's teaching on the indissolubility of marriage has been historically consistent, and that there was no precedent set in the Bible to interpret these words otherwise. Theologian
Chad Pecknold criticised Sosa's views as "reflect[ing] a profound skepticism about Holy Scripture", countering that although a variety of interpretations are allowed, they must "fit with the established doctrine of the Church and do not contradict the deposit of the Faith". Contradicting Sosa's own claim that his views were "not relativism", Catholic author
Vittorio Messori accused Sosa of "'liquefying' the Gospel itself" by suggesting that the Gospel should be adapted according to the times on the basis that Jesus's words were not recorded verbatim or "on tape". In June 2017, in an interview with
El Mundo, Sosa said, "We have formed symbolic figures such as the devil to express evil. Social conditioning can also represent this figure, since there are people who act [in an evil way] because they are in an environment where it is difficult to act to the contrary". This was criticised as contradicting the
Catechism of the Catholic Church which teaches that the
Devil is a real creature. A spokesman for Sosa later argued that Sosa was not denying church teaching, saying, "to say the devil symbolizes evil is not to deny the existence of the devil." On 21 August 2019, Sosa declared in an interview that the Devil "exists as the personification of evil in different structures, but not in persons, because [he] is not a person, [he] is a way of acting evil. He is not a person like a human person. It is a way of evil to be present in human life. [...] Good and evil are in a permanent war in the human conscience and we have ways to point them out. We recognize God as good, fully good. Symbols are part of reality, and the devil exists as a symbolic reality, not as a personal reality."
The Catholic World Report criticized these declarations, saying they were contrary to the catechism, and reminded of the controversy of the June 2017 statement of Sosa concerning the Devil. In October 2018, in an interview with
Eternal Word Television Network, Sosa argued that "the pope is not the chief of the Church, he's the Bishop of Rome". This was opposed by Chad Pecknold, Associate Professor of Theology at the
Catholic University of America, who argued that it would be wrong to believe that Pope was "merely '
first among equals'", and insisted that the pope has "
supreme authority" over all bishops and the faithful. ==Publications==
