state, church and tax in (West) Germany

[© tweed]

in his 1986 article Religion and State in Germany: West and East, theologian Jurgen Moltmann cited a few statistics that were absolutely startling to me:

The German system of religion is,  even today, a  system of  involuntary church affiliation. One is Catholic or Protestant by virtue of birth and becomes a Christian through infant baptism. Consequently, approximately 90 percent of the people in West Germany belong to a church and pay 10 percent of their income tax as church tax, but only 10 percent to 15 percent attend church regularly and remain active Christians.

so you had 90% of the adult population forking over ten percent of their income to churches that they don't even belong to beyond a personal-identity level?  I assume they get some sort of tax write-off, but, still, this startled me.

does this still go on in some form or fashion, and on a large scale in reunified Germany?
