How do you unlock the church in harvest moon island of happiness?

Make oferings to the harvest goddess by throwing items into the spring in the forest(when making offerings to the harvest goddess I suggest you use herbs, if its winter you can get white herbs at the mountain top or if you use your hoe in the mines you can find black herbs)
