Final answer:
The exact phrase 'congealed drop of sunlight' referred to by the priest was not directly cited in the provided references, but it could metaphorically refer to something that exudes great beauty or value, such as a radiant diamond.
Step-by-step explanation:
The phrase that the priest described as a 'congealed drop of sunlight' is not explicitly provided in the provided references. However, this type of metaphorical language is typical in literature to describe something of great beauty or value, often a gemstone like a diamond or piece of gold. Without a direct reference, it can be inferred that the priest might have been referring to something that embodies purity, value, or divinity, potentially symbolizing hope or redemption in a literary context. A likely candidate from the excerpts given could be the description of the diamond that appears to glow with the beam of the sun, igniting a white radiance akin to a fragment of the morning star, thus metaphorically representing a congealed drop of sunlight.
