Normally, Relics provide 4 Faith + 8 Tourism. When you are suzerain of Kandy, you get +50% Faith from Relics. Jadwiga of Poland gets an additional +2 Faith, +2 Culture, and +4 Gold from Relics. The Reliquaries religious belief triples Faith and Tourism for Relics. In a recent game (with the Spring Alexander patch), I am playing Poland. I get a Relic, which initially grants me 6 Faith. I then become suzerain of Kandy, and all my Relics now provide 9 Faith (6 * 1.5 = 9). When I found a religion and choose Reliquaries, they are now providing 27 Faith! However, if I lose suzerain status with Kandy, the Faith gets reset back to 6 Faith, where it remains even if I become suzerain of Kandy again. However, the Tourism remains correct at 24 (8 base x 3 from Reliquaries = 24), so it looks like it has something to do with the Relic calculations. (Which you might recall previously had issues with Kongo a few patches ago).
