My mother and father, for many decades now, have been fallen away Catholics. Unfortunately, their marriage of some 30 years is presumably not sacramental, as (i) my father is divorced, (ii) he did not seek an annulment, and (iii) my parents did not marry in the Church. Neither of them seem to have much interest in rectifying this situation, and they seem just as uninterested in seriously considering the claims of Catholicism in an objective and dispassionate way.
Now my question!
My folks live some 900 miles away from me, and I had planned to visit with them next week. However, I wonder something: is my visiting (and staying with) my parents in some way condoning their marital situation, and is it thus sinful on my part to do this?
