I am told all chruch records from this area are not released to government institutions or peoples and will not be ever available to public (at least in this point of time - they remain in the respective parishes.
I do not know any particulars about this area but generally many church records have been photocopied (by US Mormons for example) and placed in private or state archives, or moved entirely to state archives. Since the parish books in £apsze Wyżne have a long history (1655) and seem to be well protected the parish may as well want to continue this way.
But there are several projects where volunteers index the data from parish to parish, digitize indices and place them in public domain. This means that you can see your ancestor name there and some other details, but for the copy of the baptist or marriage certificate you still have to go either to the parish itself (and they show you which one it is) or to the state archives. Some such projects are "Poznan Project" (not your area of interest) and "Geneteka", which generally covers Małopolska province, but not this particular region of yours. Another such project "Pradziad" do not handle the £apsze Wyżne either.
So your only course of action is to do your search in situ, at the parish. This is why I attached the contact information for you. Since it is hard to do any long distance search you should find yourself a proxy person in Poland, close to £apsze if possible. Part of the search would be to find out what was a real name of Martin: Gelatka/Galetka, etc. This takes time. Nobody is going to do this sort of stuff for you voluntarily - just because you placed your appeal here, unless - with incredible luck that you might have - somebody is currently searching the parish books in £apsze Wyżne for their own purpose and is willing to handle your task as well.
A crazy suggestion: One of those schoolgirls that I previously listed might find it interesting to play a role of a little genealogist for you. She should be easy to find via gymnasium she attends. Or you may ask the priest via email about other suggestions. He might have some candidate. There might be some data protection issue, so you might need to provide some relationship proof. But historical records are usually open to public, meaning I can search any XYZ family and do not have to be in any relation to it - at least those in the state archives.
