Are you sure you want to know what it says? the writer has obviously gone to great lengths to prevent anyone from ever reading it. Who knows what dangerous content is encoded there ;o) ...
Joke aside. Here is what I would make of it:
Transkription: Anna 1653, 30. Januarii; Michael Hedlmayr, parochus; Vitus Siertl, Viti Siertl Öbermayr legitimus filius, Anna, Symonis StadlEder von Girstorf, Symonis StadlEder {Grueber}? Testes: Christophorus {P….}? zu {……..}?, Vitus Scheberl, Geörg {P…mayr}}, Casparus Eller.
Interpretation: So I would say that Vitus, son of Vitus Siertl, got married to Anna, [daughter] of Simon Stadleder of Giersdorf, on January 30th 1653 by the priest Michael Hedlmayr. The writer repeats the name Simon Stadleder for whatever reasons, maybe just to clearify that it is the one called „Grueber“. The witnesses are also given but I can not be sure of some names. Casparus Eller clearly is the „Caspar Öller, procurator“ who is witness in almost every entry.
