uther's table. He was born in 1521 and
labored in Strassburg from 1545 to 1581, the year of his death. He had
Bucer's Catechism replaced by Luther's, and entered the public
controversy against the Calvinists with a publication entitled,
_Concerning the Lord's Supper, against the Sacramentarians_, which
defends the omnipresence of Christ also according to His human nature.

In his efforts to Lutheranize the city, Marbach was opposed by the
Crypto-Calvinist Jerome Zanchi (born 1516, died 1590), a converted
Italian and a pupil of Peter Martyr [born September 8, 1500; won for
Protestantism by reading books of Bucer, Zwingli, and others; professor,
first in Strassburg, 1547 in Oxford; compelled to return to the
Continent (Strassburg and Zurich) by Bloody Mary; died November 12,
1562, when just about to write a book against Brenz]. From 1553 to 1563
Zanchi was professor of Old Testament exegesis in Strassburg. Though he
had signed the _Augsburg Confession_, he was and remained a rigid
Calvinist, both with respect to the doctrine of predestination and that
of the Lord's Supper, but withheld his public dissent until about 1561.
It was the Calvinistic doctrine of the perseverance of the saints,
according to which grace once received cannot be lost, upon which Zanchi
now laid especial emphasis. According to Loescher (_Historia Motuum_ 3,
30) he taught: "1. To the elect in this world faith is given by God only
once. 2. The elect who have once been endowed with true faith ... can
never again lose faith altogether. 3. The elect never sin with their
whole mind or their entire will. 4. When Peter denied Christ, he,
indeed, lacked the confession of the mouth, but not the faith of the
heart. _1. Electis in hoc saeculo semel tantum vera fides a Deo datur.
2. Electi semel vera fide donati Christoque per Spiritum Sanctum insiti
fidem prorsus amittere ... non possunt. 3. In electis regeneratis duo
sunt homines, interior et exterior. Ii, quum peccant, secundum tantum
hominem exteriorem, i.e., ea tantum parte, qua non sunt regeniti,
peccant; secundum vero interiorem hominem nolunt peccatum et
condelectantur legi Dei; quare non toto animo aut plena voluntate
peccant. 4. Petrum, quum negavit Christum, defecit quidem fidei
confessio in ore sed non defecit fides in corde_." (Tschackert 560;
Frank 4, 261.)

This tenet, that believers can neither lose their faith nor be eternally
lost, had been plainly rejected by Luther. In the _Smalcald Articles
