The truth about homosexual love

Invitation for academics to join our international WIKI

On the 20th of August this year the Wijngaards Institute for Catholic Research launched a new international collaborative research on homosexuality. It is entitled: ‘Gender Theologies and LGTB Catholics’.

As we have done on previous occasions we will work through an academic wiki to which academics from all over the world can contribute. We invite scholars from all relevant disciplines: moral theology, biology, sociology, psychology, etc. to join the project. We want to incorporate the latest findings of science and theological studies, and arrive at reliable well established conclusions.

The Vatican’s condemnation of homosexual acts is based on a single, simple tenet: namely, that “nature”, and specifically human biology, indicates that each and every act of sexual intercourse has reproduction (“procreation”) as its natural, biological finality. It further believes that it is always morally wrong to hinder such a biological finality, as it has been established in nature by God.

To examine this claim, our research will address the following questions:

  • What do evolutionary biology, psychology, and sociology tell us about the purposes of human sexuality, pair-bonding, and long-term socially monogamous (homo)sexual unions?
  • Is it possible to affirm that according to human biology, every act of sexual intercourse always has reproduction as its natural, biological finality?
  • What do psychology and sociology tell us about the purposes of (homo)sexual intercourse, and long-term socially monogamous (homo)sexual unions?
  • According to Catholic theology, procreation is not the primary end of marriage: rather, “the good of the couple” is. Indeed, sterile couples can legitimately marry in the Catholic Church. Similarly, with regard to fertile couples “Sexual activity […] does not […] cease to be legitimate even when, for reasons independent of their will, it is foreseen to be infertile.” (Humanae Vitae 11, 1968) Biological procreation is not understood as necessary, strictly speaking, to the existence of marriage itself. What are the consequences of this belief for the legitimacy of homosexual relationships?
  • The concept of “homosexual orientation” does not appear to be present in the Bible. What consequences does this have on the biblical passages about homosexual acts?
  • What does epigenetic and other sciences say about the etiology of sexual orientation?
  • The Vatican did not provide any evidence in support of its statement that homosexual relationships are always “harmful to the proper development of [both] human society” and the partners involved. What do psychology and sociology tell us about the consequences of LGBT relationships, and in particular long-term socially monogamous unions, on the well-being of partners and their children?

The conclusions of our research will be internationally published and submitted to the Pope and relevant departments in the Vatican.

Our latest international study on the Ethics of Contraception was widely taken note of. It even led to fruitful contacts with top officials in the Curia. We hope to achieve a similar success this time.

I would also request you to pass this invitation on to other scholars you know who are interested in the topic of homosexuality and gender theologies.
