In the early Church, I would imagine that the vast majority of martyrs were Gentile converts. Now, there is no way to prove out of the hundreds, if not thousands of Catholics killed how many were Jewish and how many were Gentile, but one can conjecture.
So, too, I am finding a holiness in young converts missing in the older generations of Catholics. I am discovering young, intelligent, holy Millennials who far outstrip their parents' generation in virtue and knowledge. They are all converts or reverts.
Grace is freely given.
God is preparing a great generation.
I can see this clearly
