Final answer:
The phrase "having a form of godliness" suggests that the individuals in question only show an outward appearance of religious devotion while neglecting the essential principles such as justice, mercy, and authentic faith.
Step-by-step explanation:
The phrase "having a form of godliness" implies that the people being described exhibit an outward appearance or semblance of religious devotion, piety, or morality, but in reality, their actions do not align with the deeper values and principles that true godliness or spiritual integrity would entail. These individuals may adhere to religious rituals or practices, but they disregard the more substantial aspects of their faith, such as justice, mercy, and faithfulness. This behavior is symbolized in one excerpt by people who profess to love God and yet are capable of heinous acts in secret, showing a stark disconnect between their public persona and private conduct.
In the context of the provided excerpts, the criticism targets those who are hypocritical in their faith, practicing religious ceremonies and expressions of belief without embodying the core teachings and moral responsibilities that come with them. This hypocrisy is illustrated by the contrasting actions of outward religious observance and the mistreatment of others, indifference to the plight of the less fortunate, or engagement in secret immoral deeds.
