I converted from Catholicism to LDS about a year ago. I can tell you that my experience with missionaries was upstanding and above board 100%. The two young men would never meet with me alone – one or two other adults were always present, and I’m in my 40s! My husband didn’t convert, but I needed his permission to get baptized. The message I received at the time of my conversion was that family was the priority, and if joining the LDS church would disrupt my family, then I wouldn’t be baptized. I’m going to go through the Temple for the first time in a few months, but I need my husband’s written permission first. That’s how much family relationships are prioritized. If my LDS activities would cause marital problems, the LDS activities take a back seat. That is directly from my Bishop and reinforced with practices I’ve witnessed over the past year. My point is, any religion can be scandalized by the acts of a few members. The catholic church should certainly understand that concept.
