“Have we — have I — thought sufficiently about the deeper and sacred meaning of everyday life?” Intriguingly, this was how Prof Jan-Albert van den Berg concluded his inaugural lecture on 28 March 2019. During this journey, Prof Van den Berg took his listeners via the scenic route, starting with a mere outline of the divine — first a sketch, then a drawing, until a fully-fledged painting emerges — ending with a manifestation of glory as seen by each individual.

Faith in popular culture

“Practical theology,” said Prof Van den Berg, “implies a specific sensitivity and feeling for the description and meaning of practice and praxis. The use of narratives is one possible way of understanding and documenting a specific involvement in praxis.”

As an object lesson from popular culture, Prof Van den Berg cited the now-infamous-yet-ultimately-beneficial amateur restoration of the Ecce Homo by octogenarian Cecilia Giménez in Borja, Spain. The original fresco, ‘Behold the Man’, was painted in 1930 by Spaniard Elías García Martínez. By 2012, the artwork had suffered the ravages of time, until Giménez’s enthusiasm for art restoration happened to it. At first, the historical society and local townsfolk were up in arms. However, since 2012, Borja’s flagging tourist industry has been revived, and the proceeds from the picture’s fame help to fund not only a local museum but a care home for the elderly as well. 

The entire debacle quickly went viral on social media and the internet, leading Prof Van den Berg to comment on the underlying significance of social media as a field of praxis. As a nod to this aspect of modern culture, he specifically used hashtags (#sketching, #drawing, #painting, #tweetingGod, #findingthesacred) for the subtitles of his lecture. He said, “This is how the Twitter world in particular talks about God, in order to express multiple and compound understandings of daily life.” 

Evergreen Bible student

Prof Van den Berg’s love of practical theology dated back to his days as a student, when he said he learnt that “theology was not just a noun but a verb”. He said: “Practical theology’s description of the Divine in everyday life represents, for me, the relevance and topicality with which I associate theology.” He added that the title of his inaugural lecture directly relates to this understanding, as much as it can be strongly associated with his recent doctoral thesis at the University of Queensland, entitled Tweeting God: A practical theological analysis of the communication of Christian motifs on Twitter.

Expressions of faith in the mundane

In answering his question, mentioned at the outset, Prof Van den Berg said: “Perhaps there is more to be seen, heard, and read in everyday-life texts of the Cecilias of the world who take up their ‘paintbrushes’ ”. Stating that formal theological language has, in certain aspects, lost some of its impact and that many people have turned a deaf ear to the articulation of these truths, Prof Van den Berg concluded that “one must envision possible alternative descriptions, in the form of existing practices of #tweetingGod, finding the sacred in everyday life”.

Several industries in South Africa are currently producing hundreds of thousands of tons of carbon dioxide a year, which are released directly into the air. A typical family sedan doing around 10 000 km per year, is annually releasing more than one ton of carbon dioxide into the atmosphere.

The Inorganic Chemistry Research Group in the Department of Chemistry at the University of the Free State (UFS), in collaboration with the University of Zurich in Switzerland, has focused in recent years on using carbon dioxide – which is regarded as a harmful and global warming gas – in a meaningful way. 

According to Prof André Roodt, Head of Inorganic Chemistry at the UFS, the Department of Chemistry has for the past five decades been researching natural products that could be extracted from plants. These products are manufactured by plants through photosynthesis, in other words the utilisation of sunlight and carbon dioxide, nitrogen, and other nutrients from the soil.

Caffeine and chlorophyll 
“The Inorganic group is systematically researching the utilisation of carbon dioxide. Carbon dioxide is absorbed by plants through chlorophyll and used to make interesting and valuable compounds and sugars, which in turn could be used for the production of important new medicines,” says Prof Roodt.

Caffeine, a major energy enhancer, is also manufactured through photosynthesis in plants. It is commonly found in tea and coffee, but also (artificially added) in energy drinks. Because caffeine is a stimulant of the central nervous system and reduces fatigue and drowsiness, some people prefer decaffeinated coffee when enjoying this hot drink late at night. 

Removing caffeine from coffee could be expensive and time-consuming, but also environmentally unfriendly, because it involves the use of harmful and flammable liquids. Some of the Inorganic Group’s research focus areas include the use of carbon dioxide for the extraction of compounds, such as caffeine from plants. 

“Therefore, the research could lead to the availability of more decaffeinated coffee products. Although decaffeinated coffee is currently aromatic, we want to investigate further to ensure better quality flavours,” says Prof Roodt.

Another research aspect the team is focusing on is the use of carbon dioxide to extract chlorophyll from plants which have medicinal properties themselves. Chemical suppliers sell chlorophyll at R3 000 a gram. “In the process of investigating chlorophyll, our group discovered simpler techniques to comfortably extract larger quantities from green vegetables and other plants,” says Prof Roodt.

Medicines
In addition, the Inorganic Research Group is also looking to use carbon dioxide as a building block for more valuable compounds. Some of these compounds will be used in the Inorganic Group’s research focus on radiopharmaceutical products for the identification and possibly even the treatment of diseases such as certain cancers, tuberculosis, and malaria.
