Blind people marry and have children, as do others who rely on public services or other people for other reasons (including that they are not inclined to learn to drive), so being visually impaired does not mean you do not have a vocation to marry or to have children. Whether it would impede the educational attainment necessary for the priesthood would depend on the nature and extent of the visual impairment. To my knowledge, there is no prohibition, per se, on a blind or deaf man being ordained, nor are the blind or deaf summarily prohibited from monasteries or convents. It depends on whether your collection of gifts and challenges is a good match.
Since it was not that long ago that the internet did not exist and only a lunatic would look for a suitable spouse among the strangers to be found amusing themselves at drinking establishments, it is obviously not necessary to cruise bars or otherwise seek the acquaintance of total strangers in order to marry. I would suggest that getting to know the friends and relatives of people you know and admire or simply making friends among those who also spend their time in prayer and in service of the Church and of the poor is a surer route to finding those who are likely to be suitable spouses or who will introduce you to likely candidates. You might also want to look for chances to work alongside members of religious communities or to go on discernment retreats offered by a religious order that might interest you. Sometimes finding your vocation is a matter of always seeking to do the will of God one day at a time, and realizing over time whether you can follow that path best in a religious community, as a single person free to serve your parish without other attachments, or as a married person sharing a single life with a spouse with whom you will welcome whatever children God may send you, and the responsibilities particular to that state of life. In short, don’t wait to do God’s will until you’ve found your “vocation”. Look to serve God and neighbor on a daily basis (and look after yourself in a prudent manner as part of that), and let that lead you to your particular state in life. It is certainly a better way to find a holy spouse than wasting time and money in a bar or a club when neither is a place of relaxation that even interests you or your trusted friends. Bars and clubs are moral for people who enjoy them and have some limited amount of spare money and time to spend there, but there is no reason for the disinterested to cultivate an interest in them!! You’d just find someone who enjoys clubs, and what good would that be? Spend time doing what you ought to do and, in your leisure time, what you really enjoy doing with people whose company really refreshes you, and you’ll have a better chance of finding someone whose natural inclination is to do the same sort of things, instead of things that bore you or make you uncomfortable.
That was a wordy way to put it, but that’s what I’d advise.
), and you get some information on the woman – such as photo, age, location, values, interests, job – before you decide to write to her.
probably in the way a aunt would tell a nephew or mother would tell a friend of her son I am guessing. Not that I have anything againts middle aged women but im only 28! I wanna hear that from women my own age!
