WYSIWYG, as noted above, Reformed Academic and English Church Latin pronunciations usually are different. The vowels are not the same, neither are the vowel combinations.
Reformed Academic a, e, i, o, u = aah, ay, ee, oh, ooh.
To go on to the combinations, oe is pronounced as in toil in Reformed Academic but generally pronounced as in bee in traditional English or church English.
Consonants vary as well; c in R.A. as adopted by classical scholars is always pronounced as in cat (centum is always Kentum, etc. Cae is ky, Caesar is pronounced Kaiser. In other words, there is a split in pronunciation.
Having worked in systematic botany and paleontology, I use Reformed Academic. I would presume your husband would not use these pronunciations since they would confuse the congregation.
