1. "Astor" refers to the Astor family, a well-known American family from the 19th and early 20th centuries who were renowned for their wealth and power. They worked in finance, politics, and real estate, among other industries. I tried my best to partly associate my moniker "Astor" with materialistic values here.
2. In general, and especially in Christian faiths, "Pastor" designates a religious authority. Pastors are in charge of directing religious services and activities, guiding congregations, and giving spiritual advice.
By combining these two values, "TheAstorPastor" means a person who demonstrates a combination of spiritual leadership (connected to being a pastor) and worldly money or influence (related to the Astor dynasty).
