There are quite a few different alternatives you can try. If your church already has a blog or Facebook page, you're halfway there. You could use Google Drive to post the audio files. The good thing about Google Drive is that it will take very large file sizes, so uploading the file shouldn't be a problem. The other options to try are Soundcloud or YouTube. Just post the audio, and then use the share links to post to your Facebook page or website.
