What does “um…” mean. I’m German and don’t know

Well, Küng was highly honored by the Free Masons. Free-Masons and Catholic Church is contrary. A membership for Catholics not allowed; see “Declaratio de associationibus massonicis” of 26th of Nov. 1983. Küng fought that declaration fiercely. In any case: Most Küng (who owns no valid teaching permission in any Catholic educational institution) taught and claimed, was and still is pure heretic and anti-Church, which he calls a misled establishment. Of course modernists adore him. But they then see “CHURCH” rather as a social institution than as what it is; Jesus Christ’s foundation for closer connection to God. And Jesus founded but one Church - the Catholic one. Named as such ever since St. James’ “Catholic Letters” (and even before that).
For many decades, true Catholics see Hans Küng’s destructing work as just as annoying and destructice and leading astray, as that of Drewermann.

Both however are adored by as well modernists as atheists.
