Insults are in the eye of the beholder.
Many people are 'insulted' when confronted with the truth and choose to remain ignorant.
I agree.
When Catholics need your idiosyncratic views of Scripture to inform us as to Catholicism or less complete forms of Christianity, we will be sure to let you be the first to know. St. Paul came along about 1500 years before Luther suddenly imagined himself called to "reform" the Catholic religion founded and guaranteed by the promises of Jesus Christ Himself. St. Paul is a standard under Jesus Christ. Luther is a deviation.
As to "ancestor" "worship", there are two elements. First St. Paul would have to qualify as an ancestor. He was a bishop if ever there was one. According to some folks, that suggests that he must have been at least a husband and possibly a father. Name his wife and each of his children.
Second, there is the matter of "worship." Definition please.
Next, there is a rather sizable Lutheran Church in a community near me, so sizable that it has an inner city location as well as a much larger location in a nicer location. Each is called St. Paul's Lutheran. Are the good folks of those congregations running a risk of "ancestor worship???" Should they rename their facilities Harvest Moon Lutheran or whatever???? Likewise, Episcopalians have the Cathedral of St. John in NYC.
More importantly, who died and left you or your fellow reformists in charge of preaching your respective curious idiosyncrasies as to Scripture at Catholics????
You don't actually believe that any adequately catechized Roman Catholic is going to swap the Truth and the guarantees and promises of Jesus Christ and the Mass and the 7 sacraments established by Him for the choice of some cult among tens of thousands in the reformed stew of idiosyncratic and often conflicting "Scriptural" interpretations by each and every reformed Tom, Dick and squabbling Harriet with a Bible, some reading lessons and an agenda and a half, do you???
We Catholics draft no one much less you. Go preach to your own. Do you actually think you perform a service by dividing conservatives on websites such as this???
