Postel was born in Freiburg, Lower Saxony, the son of the theologian Lorenz Postel and his wife Dorothea, née Isentrut. His father was a minister at the Heiliggeistkirche in Hamburg. Christian Heinrich Postel attended the Gelehrtenschule des Johanneums. He studied law at the University of Leipzig from 1680 with Christian Thomasius. When the plague threatened Leipzig, he continued his studies at the University of Rostock, where he graduated as a licentiate on 10 May 1683. He travelled for six months with, a historian and theologian, in the Netherlands, England and France. Their diary of the journey, "Beschreibung einer Reise durch das nordwestliche Deutschland, nach den Niederlanden und England im Jahre 1683", not printed until the 19th century, shows their many interests, especially in foreign universities and libraries. Back in Hamburg, he opened an office as a lawyer. He wrote 28 opera libretti for the Oper am Gänsemarkt from 1688 to 1702, set by contemporary composers such as Johann Georg Conradi, Reinhard Keiser and Johann Sigismund Kusser. Georg Philipp Telemann set his libretto of Sieg der Schönheit. He adapted Jean Galbert de Campistron's tragedy Achille et Polyxène for an opera by Lully and Colasse, premiered in 1687, as a French-German cooperation unique in opera history. His opera librettoDie heilige Eugenia, oder die Bekehrung der Stadt Alexandria zum Christenthum, was set by Johann Philipp Förtsch, premiered in 1688 and printed in 1695. Around 1700, Postel wrote the libretto for an oratorioLeiden und sterben Jesu Christi. A setting formerly attributed to George Frideric Handel is now believed to be by Christian Ritter. Another setting, called Das Lied des Lammes is by Johann Mattheson. Several parts of the text were used in Bach's St John Passion. While Postel is thought to have written all thirteen poetic pieces added to the Gospel text, it is certain only for three which were reprinted by Christian Friedrich Hunold, while "Durch dein Gefängnis, Gottes Sohn" is among the other ten. Ritter and Mattheson composed it as an aria, while Bach set it as a chorale on the melody of the hymn "Machs mit mir, Gott, nach deiner Güt". All three composers place it at the same position in the action, in the court hearing of Pilate. Postel died in Hamburg of consumption.
