The word translated as "faith" in English-language editions of the New Testament, the Greek word "πίστις" ("pístis"), can also be translated as "belief", "faithfulness", or "trust". Christianity encompasses various views regarding the nature of faith. Some see faith as being persuaded or convinced that something is true. In this view, a person believes something when they are presented with adequate evidence that it is true. The theologian Saint Thomas Aquinas did not hold that faith is mere opinion: on the contrary, he held that it represents a mean (understood in the Platonic sense) between excessive reliance on science (i.e. demonstration) and excessive reliance on opinion.
