The answer
As His Holiness said, it is not preferable, as cultural differences may result in problems. It is better to choose your partner from amongst your society, so that there will be similar mentality and culture, and a better opportunity of getting to know each other. Most importantly, however, you must pray - not in order to choose, for if you choose by yourself you will be confused. The Lord knows who your partner will be, and so, you pray in order to discover - discover what the Lord wills for you. Pray so that the Lord may enlighten your vision and your footsteps.
