Nothing against cradle Catholics because I sense their fervency for Jesus and the Catholic Church and respect them a great deal, but I generally relate more to converts who come from a similar background as mine because they understand both faith traditions from personal experience and are able to explain things (compare and contrast) in ways I can better understand.
In my dealings on CAF, Protestant converts to Catholicism generally don’t repudiate their former faith but usually show appreciation for the good things in it that they learned/experienced — but also see Catholicism as an enhancement to their Christian faith journey and see Catholicism as the “fullness of faith” and a means to making their faith more well-rounded. I can dialogue with these folks in good faith.
Some cradle Catholics understand this as well and are respectful but unfortunately there are those who, in their zeal to defend Catholicism, actually (perhaps unknowingly) push potential converts away through frequent sectarian comments that denigrate non-Catholic Christian faith traditions. For example, if a person disrespects my faith tradition to the point of saying God’s presence doesn’t even abide in my sanctuary, that person obviously doesn’t know my faith or congregation and doesn’t care to understand it so we have nothing else to discuss. However, if they treat me as a fellow Christian who could benefit from Catholicism, then we can have a dialogue and proceed from there.
