The Gospel of Thomas is not included in the Bible due to its reliance on the content found in the canonical Gospels, which are widely regarded as the earliest Christian manuscripts. In terms of theology, the Gospel of Thomas differs from the Gospels in the New Testament. For example, the synoptic Gospels are more inclusive of women in religious practices, allowing them to attain salvation. In contrast, the Gospel of Thomas emphasizes the need for women to adopt a male spirit (114:2 and 3). Despite its exclusion from the Bible, the Gospel of Thomas holds significant importance as a valuable resource for understanding early Christian beliefs. It consists of a collection of sayings attributed to Jesus during his lifetime. In conclusion, the Gospel of Thomas is renowned as the most well-known gospel that did not make it into the Bible. Nevertheless, it remains a valuable source of information regarding the early Christian faith.
