Final answer:
Captain Webb bought a Mason's lodge or temple building to serve as a Methodist church in Philadelphia.
Step-by-step explanation:
The building bought by Captain Webb to serve as a Methodist church in Philadelphia was a Mason's lodge or temple. This building is an example of how secular and religious practices mimic each other.
It was used as a Methodist church where religious services were held. Methodism, founded by John Wesley in the 18th century, did experience growth and expansion in North America, with Methodists establishing churches and congregations.
However, it's essential to note that Masonic lodges or temples and Methodist churches are distinct institutions with different purposes. Masonic lodges are fraternal organizations associated with Freemasonry, a fraternal and charitable society.
Masonic temples are the buildings or meeting places where Masonic lodges conduct their meetings and ceremonies. Freemasonry is not a religion, but it often includes spiritual and moral teachings.
