Dear WieKo68, to make this very clear, the websites you are taking the data from must either explicitly allow the use in OSM, or at least have an open license without strict attribution rules and without a prohibition on commercial use. If the web site says something like "data is under CC-BY-SA" or "data is free for personal use" then it is not suitable. In your future contributions, please use the changeset source field to provide links to the relevant web sites so that everyone can read the license themselves. (Do not provide a link to the homepage of the church - provide a link to the precise page where you downloaded the data.)

Also, as I said, please stop adding name tags to boundary ways even if it is only temporary. You are using OSM as a staging tool to help you manage your import process and that is not how imports work!

Both of these comments will certainly have been made by other mappers with whom you have discussed this data import, as required by the import guidelines!
