Final answer:
The Trinitarian Formula was not used in Baptism early in the second century as indicated in Paul's letters in the New Testament.
Step-by-step explanation:
The statement that Paul's letters in the New Testament indicate that the Trinitarian Formula was used in Baptism early in the second century is false.
The Trinitarian Formula refers to the Christian belief in the threefold nature of God - the Father, Son, and Holy Spirit. While there are references to baptism in Paul's letters, there is no direct mention of the Trinitarian Formula in his writings.
It was not until later in the history of Christianity, particularly during the Council of Nicaea in 325 AD, that the Trinitarian Formula became officially recognized and widely accepted.
