228. 19. Various similar qualities can be joined together, but not with dissimilar ones. Instances of similarities are many and various, and some of them are further apart, some less so. Yet even those that are further apart can in time be joined by various means, especially by a couple's accommodations to one another's wishes, by their performance of mutual duties, by their courteous treatment of each other, by their refraining from things unchaste, by their joint love of little children and care for their children; but above all, by their conformity in matters connected with the church. For through matters connected with the church a joining of distant similarities is achieved inwardly, and only outwardly through other means.
No conjunction, however, can be achieved with dissimilar qualities, because they are incompatible.
