Final answer:
Early Methodists were named for their methodical approach to worship and religious life, which makes the statement true. They adhered closely to Bible study and practiced a disciplined lifestyle, leading to the nickname 'Methodists'.
Step-by-step explanation:
The statement that early Methodists were called that because they were so methodical is indeed true. This denomination was founded in the 18th century by John Wesley and his brother Charles Wesley. They developed a methodical approach to Bible study and religious observances, which included strict adherence to the Scripture and a disciplined lifestyle. This systematic approach to their religious life earned them the nickname 'Methodists'. The Methodist movement emphasized the importance of a disciplined and orderly way of life and worship, hence the term 'Methodist' adequately reflected their methodical procedures.
