Faculty of Theology and Religion opening
Present at the Faculty of Theology and Religion’s Theology Day were from the left: Dr Eugene Fortein, Dr Siphiwe Dube, Prof Rantoa Letšosa, and Prof Charlene van der Walt.

This year, the Faculty of Theology and Religion at the University of the Free State (UFS) resumed its annual tradition of celebrating the new academic year, after being halted by the COVID-19 pandemic in 2020.

The focus was on a theology of vulnerability for our times, with the theme supported by the text verse from 2 Corinthians 4:7: “We have this treasure in clay jars.” 

God embodies vulnerability

Dean of the faculty, Prof Rantoa Letšosa, left delegates with the inspiring message that one of the treasures in these clay jars is the power of God; power that enables us to stand strong and move forward in trying circumstances, such as the COVID-19 pandemic. He wished all attendees, both in person and online, to experience this extraordinary strength and power of God in the new year. 

Prof Rian Venter from the Department of Historical and Constructive Theology, who led the worship service, talked about humanity that has achieved so much – in the areas of health, space, communication, transport, etc. “Despite all these achievements, we are more insecure, with an intensified sense of vulnerability,” he said. 

“However, the One in whom we believe as our Saviour and Lord is a vulnerable God; he embodied vulnerability. We cannot talk about God as if he is not affected by our vulnerability. He is love. He is affected by us,” he said. 

Depriving people of humanity 

But to be vulnerable can also be seen as to be weak, defenceless, open to harm, in need of care, and deprived of one’s humanity. 

Dr Siphiwe Dube from the University of the Witwatersrand integrated the topic of vulnerability into the paper he delivered, speaking from a decolonialism point of view on the research topic: Towards a Decolonial Political Theology of Vulnerability: Reflections from the Margins. In one of his statements, he said that black people are living in the reality constructed for them and have not discovered what blackness is. He urged the young attendees to make use of spaces created for discussion of this matter. 

Bringing to the table another perspective on this topic, was Prof Charlene van der Walt from the School of Religion, Philosophy and Classics at the University of KwaZulu-Natal. Her paper was on the othering, stigmatisation, and exclusion experienced by the LGBTIQA+ people in the African context in general and the African faith communities in particular. She connected the shame experienced by queer people in a family setting to the story of Joseph in the book of Genesis in the Bible. In her paper: Reflecting on Joseph in the context of Izitabane vulnerability, violence, identity erasure and the imperative of recognition and accompaniment, she stated that Joseph’s otherness informed the vulnerability, exclusion, violence, and identity erasure that happens within the confines of family. 

According to Prof Van der Walt, she wished to not argue for LGBTIQA+/ Izitabane people to be seen or that they somehow ‘pass’ and slip below the radar, but that the recognition called for implied a different kind of seeing: it implied a compassionate witnessing and a humanising recognition. “It implies process, interrogation of power, empathy and imagination, weeping and a commitment to community,” she said. 

Another interesting perspective on the theology of vulnerability was that of Dr Eugene Fortein from the Department of Historical and Constructive Theology at the UFS. In his paper on Vulnerability by Design: On a Theology of Prophetic Solidarity, he asked why the vulnerable is vulnerable? What led to them being vulnerable?
 
“The presence of the vulnerable in South Africa is not an accident. It is not because of fate, but because of a design that is 370 years in the making; deliberately to keep people poor for generations to come.” 

He said it started with Jan van Riebeeck. Legislation such as the Natives Land Act of 1913, the Group Areas Act of 1950, and the Bantu Education Act of 1953 also played a key role. “These were designed to oppress one group and enabling the other to thrive.”

“The scars of this legislation are still haunting us today,” he said. 

The One in whom we believe as our Saviour and Lord is a vulnerable God; he embodied vulnerability. We cannot talk about God as if he is not affected by our vulnerability. He is love. He is affected by us. – Prof Rian Venter

“The vulnerable have names and faces. They are experiencing the effects of being vulnerable on their bodies and that is not to be taken lightly.”

“Do not only pray for the poor and the vulnerable, but work actively to bring restitution,” he said. The church now has the opportunity to be a true servant of Christ,” Dr Fortein added.

Research eradicates bacteria from avocado facility

“The aim of my project was to identify and characterise the contamination problem in an avocado-processing facility and then to find a solution,” said Dr Amy Strydom, postdoctoral fellow in the Department of Microbial Biochemical and Food Biotechnology at the University of the Free State (UFS).

Her PhD, “Control of Listeria monocytogenes in an Avocado-processing Facility”, aimed to identify and characterise the contamination problem in a facility where avocados were processed into guacamole. Dr Strydom completed her MSc in food science in 2009 at Stellenbosch University and this was the catalyst for her starting her PhD in microbiology in 2012 at the UFS. The research was conducted over a period of four years and she graduated in 2016. The research project was funded by the National Research Foundation.

The opportunity to work closely with the food industry further motivated Dr Strydom to conduct her research. The research has made a significant contribution to a food producer (avocado facility) that will sell products that are not contaminated with any pathogens. The public will then buy food that is safe for human consumption.


What is Listeria monocytogenes?

Listeria monocytogenes is a food-borne pathogenic bacterium. When a food product is contaminated with L. monocytogenes, it will not be altered in ways that are obvious to the consumer, such as taste and smell. When ingested, however, it can cause a wide range of illnesses in people with impaired immune systems. “Risk groups include newborn babies, the elderly, and people suffering from diseases that weaken their immune systems,” Dr Strydom said. The processing adjustments based on her findings resulted in decreased numbers of Listeria in the facility.

The bacteria can also survive and grow at refrigeration temperatures, making them dangerous food pathogens, organisms which can cause illnesses [in humans]. Dr Strydom worked closely with the facility and developed an in-house monitoring system by means of which the facility could test their products and the processing environment. She also evaluated bacteriophages as a biological control agent in the processing facility. Bacteriophages are viruses that can only infect specific strains of bacteria. Despite bacteriophage products specifically intended for the use of controlling L. monocytogenes being commercially available in the food industry, Dr Strydom found that only 26% of the L. monocytogenes population in the facility was destroyed by the ListexP100TM product. “I concluded that the genetic diversity of the bacteria in the facility was too high and that the bacteriophages could not be used as a control measure. However, there is much we do not understand about bacteriophages, and with a few adjustments, we might be able to use them in the food industry.”

Microbiological and molecular characterisation of L. monocytogenes

The bacteria were isolated and purified using basic microbiological culturing. Characterisation was done based on specific genes present in the bacterial genome. “I amplified these genes with polymerase chain reaction (PCR), using various primers targeting these specific genes,” Dr Strydom said. Some amplification results were analysed with a subsequent restriction digestion where the genes were cut in specific areas with enzymes to create fragments. The lengths of these fragments can be used to differentiate between strains. “I also compared the whole genomes of some of the bacterial strains.” The bacteriophages were then isolated from waste water samples at the facility using the isolated bacterial strains. “However, I was not able to isolate a bacteriophage that could infect the bacteria in the facility.
