ue the whole question as to the right and wrong of
indulgences by means of his theses. His sermon _Of Indulgences
and Grace_, occasioned by Tetzel's attack and delivered in the
latter part of March, 1515, as well as his sermon _Of Penitence_,
delivered about the same time, were also intended for his
congregation. Before his congregation (Sept., 1516-Feb., 1517) he
delivered the _Sermons on the Ten Commandments_, which were
published in 1518, and the _Sermons on the Lord's Prayer_, which
were also published in 1518 by Agricola. Though Luther in the
same year published a series of controversial writings, which
were occasioned by attacks from outside sources, viz., the
_Resolutiones disputationis de virtute indulgentiarum_, _the
Asterisci adversus obeliscos Joh. Eccii_, and the _Ad dialogum
Silv. Prieriatis responsio_, still he never was diverted by this
necessary rebuttal from his paramount duty, the edification of
the congregation. The autumn of the year 1518, when he was
confronted with Cajetan, as well as the whole year of 1519, when
he held his disputations with Eck, etc, were replete with
disquietude and pressing labors; still Luther served his
congregation with a whole series of writings during this time,
and only regretted that he was not entirely at its disposal. Of
such writings we mention: Explanation of the Lord's Prayer for
the simple Laity (an elaboration of the sermons of 1517); Brief
Explanation of the Ten Commandments; Instruction concerning
certain Articles, which might be ascribed and imputed to him by
his adversaries; Brief Instruction how to Confess; Of Meditation
on the Sacred Passion of Christ; Of Twofold Righteousness; Of the
Matrimonial Estate; Brief Form to understand and to pray the
Lord's Prayer; Explanation of the Lord's Prayer "vor sich und
hinter sich"; Of Prayer and Processions in Rogation Week; Of
Usury; Of the Sacrament of Penitence; Of Preparation for Death;
Of the Sacrament of Baptism; Of the Sacrament of the Sacred Body;
Of Excommunication. With but few exceptions these writings all
speared in print in the year 1519, and again it was the
congregation which Luther sought primarily to serve. If the
bounds of his congregation spread ever wider beyond Wittenberg,
so that his writings found a surprisingly ready sale, even afar,
that was not Luther's fault. Even the _Tessaradecas
consolatoria_,[2] written in 1519 and printed in 1530, a book of
consolation, which was originally intended for
