You have chosen an interesting topic when you get into the Prosperity Gospel.
Yes, it's an incorrect interpretation of what God wants for us. But people who are grasping at riches for their own sake, have often found that particular doctrine wanting in the end.
Indeed, the only people who seem to be prospering from the Prosperity Gospel, are the preachers.
While poverty does not guarantee holiness, it is worth noting that many great Christians going back to St. John the Baptist, whose Nativity was commemorated on Friday, a day of rejoicing for those of us who oppose abortion, and St. Anthony the Great, and the great mendicant friars of the Western Church during the 13th century, not just St. Dominic, who I admire greatly, and Francis of Assisi, but the lesser known mendicants like the founders of the Carmelites, the Servites, the Minims, and the ransoming orders, the Mercedarians and Trinitarians (who I also particularly like), who embraced poverty so that the funds they collected could be used to pay the ransom of Christians abducted from ships and to an even greater extent, coastal roads in Italy and around the Mediterranean, by marauding Islamic pirate-terrorists, something we in recent years experienced again with the piracy in Somalia, but whereas we were blessed with naval forces to counter the pirates, 13th century Europe was poor and technologically and militarily often at a disadvantage to Muslims.
Likewise, more recent ascetics embraced poverty, such as the Holy Fool St. Basil the Blessed, who gave raw meat to Ivan the Terrible as a rebuke to the Czar for his brutality, and the hermit St. Seraphim of Sarov.
However God includes wealthy Christians in his plan for salvation, but their vocation is more difficult, but not impossible, as Christ points out with his discourse with the young rich man recorded in the Synoptics.
The message of the Prosperity Gospel that Christians should expect Earthly wealth as the reward for their faith directly and obviously contradicts the New Testament. Its a bit like the Unitarianism of Soccinius and other Sola Scriptura Unitarians, even as late as William Ellery Channing, which lacks even the remote possibility of Arianism. It is a direct contradiction, which exploits the ignorance of pious middle class and lower middle class Christians who are poorly catechized, not well versed in scripture, forgetful, and often financially desperate, hoping for divine deliverance from poverty, which is a possibility, but they are being deceived by charlatans who seek to enrich themselves at the expense of those under financial strain.
Given the increased poverty caused by Covid and the inflationary crisis, I believe the prosperity gospel preachers, especially the more subtle ones, are likely to expand.
I myself oppose even passing the collections plate during church services; it is not a rubric of the ancient liturgical texts, and it is not an offertory, in the original sense of the word: in the early church, the Offertory was a procession of the unconsecrated bread and wine to the altar before the Eucharist, and this has been revived in Anglicanism, but has never ceased to be the practice of the Eastern churches, occurring at the start of the liturgy in the Coptic Rite, and in the Byzantine Rite, during the Great Entrance. I also think alms should not be placed directly on the Holy Table for blessing, but rather discrete places for people to give alms should be placed in the church, and at appropriate times these should be collected and a prayer of thanks given for them, and then they should accounted for along with voluntary oblations or tithes given by parishioners of means, and these should then be distributed, with those needed to cover ecclesiastical expenses set aside and the rest distributed to charity in a transparent manner according to a transparent integrated spending plan for both the costs of running the church and the charitable giving, agreed by the congregation, so the alms reach those who need them with a minimum of delay and bureaucracy. Of course, the larger the church, the more delay and bureaucracy is inevitable and necessary to counter the diabolical acts of embezzlers, fraudsters and simonists, but this is counteracted by the larger amounts being given. The Roman Catholic Church for example is the world’s largest charitable donor.
