The son of a Swabian priest, he studied in Adelberg and after school visited the lower Konvikts in Maulbronn at the Tübinger Stift, where he met Johann Valentin Andreae.

After a post as senior deacon in Kirchheim unter Teck in 1612, he was "Ephorus" of the Evangelical College of St. Anna in Augsburg.

As a follower of the Concord, he defended the forerunner of Pietism, Johann Arndt, in the confrontation about the orthodoxy of his teachings.

In 1626 he published under the pseudonym Rupertus Meldenius a work entitled Paraenesis votiva per Pace Ecclesia ad Theologos Augustana Confessionis auctore Ruperto Meldenio Theologo (A Reminder for Peace at the Church of the Augsburg Confession of Theologians), in which he argued for peace among the contending parties and unity within the meaning of the Concord, and called for the practice of charity (i.e. Christian love), saying: which later developed into the phrase "In necessariis unitas, in dubiis libertas, in omnibus caritas" (In essentials unity, in doubtful things/non-essentials liberty, in all things charity[1]).
