APA style does not make specific reference to Homilies, however, as the content is not published or posted anywhere and the Priest is the only source of the information, they can be viewed in a similar way to lectures and these are cited as personal communications.
The in-text reference should cite the communicator's initial and surname, a title to explain the type of communication, and the date of the communication. For example:
Fr S. Fernando (Homily, 18 May, 2016) explained...
As the information cited is not retrievable, it is not included in the reference list.
