=== Scientific writings ===
During his career, Teilhard published many dozens of scientific papers in scholarly scientific journals. When they were published in collections as books, they took up 11 volumes. John Allen Grim, president of the American Teilhard Association and the co-founder and co-director of the Yale Forum on Religion and Ecology, said: "I think you have to distinguish between the hundreds of papers that Teilhard wrote in a purely scientific vein, about which there is no controversy. In fact, the papers made him one of the top two or three geologists of the Asian continent. So this man knew what science was. What he's doing in The Phenomenon and most of the popular essays that have made him controversial is working pretty much alone to try to synthesize what he's learned about through scientific discovery - more than with scientific method - what scientific discoveries tell us about the nature of ultimate reality.” Grim said those writing were controversial to some scientists because Teilhard combined theology and metaphysics with science, and controversial to some religious leaders for the same reason.

=== Service in World War I ===
Mobilized in December 1914, Teilhard served in World War I as a stretcher-bearer in the 8th Moroccan Rifles. Priests were mobilized in the France of the First World War era, and not as military chaplains but as either stretcher-bearers or actual fighting soldiers.  For his valor, he received several citations, including the Médaille militaire and the Legion of Honor.
During the war, he developed his reflections in his diaries and in letters to his cousin, Marguerite Teillard-Chambon, who later published a collection of them. (See section below) He later wrote: "...the war was a meeting... with the Absolute." In 1916, he wrote his first essay: La Vie Cosmique (Cosmic life), where his scientific and philosophical thought was revealed just as his mystical life. While on leave from the military he pronounced his solemn vows as a Jesuit in Sainte-Foy-lès-Lyon on 26 May 1918. In August 1919, in Jersey, he wrote Puissance spirituelle de la Matière (The Spiritual Power of Matter).
At the University of Paris, Teilhard pursued three unit degrees of natural science: geology, botany, and zoology. His thesis treated the mammals of the French lower Eocene and their stratigraphy. After 1920, he lectured in geology at the Catholic Institute of Paris and after earning a science doctorate in 1922 became an assistant professor there.

=== Research in China ===
In 1923 he traveled to China with Father Émile Licent, who was in charge of a significant laboratory collaboration between the National Museum of Natural History and Marcellin Boule's laboratory in Tianjin. Licent carried out considerable basic work in connection with Catholic missionaries who accumulated observations of a scientific nature in their spare time.
Teilhard wrote several essays, including La Messe sur le Monde (The Mass on the World), in the Ordos Desert. In the following year, he continued lecturing at the Catholic Institute and participated in a cycle of conferences for the students of the Engineers' Schools. Two theological essays on original sin were sent to a theologian at his request on a purely personal basis:

Chute, Rédemption et Géocentrie (Fall, Redemption and Geocentry) (July 1920)
Notes sur quelques représentations historiques possibles du Péché originel (Note on Some Possible Historical Representations of Original Sin) (Works, Tome X, Spring 1922)
The Church required him to give up his lecturing at the Catholic Institute in order to continue his geological research in China. Teilhard traveled again to China in April 1926. He would remain there for about twenty years, with many voyages throughout the world. He settled until 1932 in Tianjin with Émile Licent, then in Beijing. Teilhard made five geological research expeditions in China between 1926 and 1935. They enabled him to establish a general geological map of China.
In 1926–27, after a missed campaign in Gansu, Teilhard traveled in the Sanggan River Valley near Kalgan (Zhangjiakou) and made a tour in Eastern Mongolia. He wrote Le Milieu Divin (The Divine Milieu). Teilhard prepared the first pages of his main work Le Phénomène Humain (The Phenomenon of Man). The Holy See refused the Imprimatur for Le Milieu Divin in 1927.
