By this time too Zwingli had begun to develop his
characteristic Eucharistic doctrine, which diverged signif-
icantly from that of LUTHER. In rejecting TRANSUBSTANTIA-
TIONZwingli also rejected any sort of REAL PRESENCE,
expounding a purely symbolic interpretation of the sacra-
ment. The ensuing conflict between the two men, which a
personal meeting (see MARBURG, COLLOQUY OF) could not
resolve, led to a permanent division between the Swiss
and German strands of Protestantism. Zwingli remained
until his death the key figure in the Swiss Reformation,
and played a leading role in the promotion of Protes-
tantism in the other Swiss cantons.
