There is no one answer to your question. Here are a few of the reasons:
The easy answer is tradition!- a Long-standing custom. It is true many religious orders, to which the Nuns belong ( there being no lay or unattached sisters) were founded by Men such as Saint Francis and St. Dominic- hence Franciscans, Dominicans. oddly there are more female than male saints- so there is no shortage of religious names without any Gender- hopping. Sometimes they will combine male and female names- such as a Sister Martin Mary of the IHM. ( no, she did not invert the name of the actress Mary Martin. Mary is of course the Blessed Virgin- but Martin is a male saint. You will also find such combinations as Mary Luke, and more normal-like male names adapted to a female role- I knew of a Sister Roberta. I suggest you ask about at a local convent or religious book store , they could shed some light on this veiled tradition, no pun intended. By the way both Sister Martin Mary and Sr. Roberta were both in the same order, the IHM ( Immaculate Heart of Mary).
Nuns do not go through Holy Orders. They take certain vows to become nuns.
Yes
just take the number of teams in NCAA and times that by 13
No. Widows are women whose husbands have died. Nuns are "brides of Christ" who take vows and practice "poverty, chastity, and obedience".
Like priests, nuns take a vow of chastity
members of orders proper (such as the Society of Jesus) take solemn vows. "OP" stands for "Order of Preachers" and is specific to Dominicans. Thus the sisters you are referring to are probably Dominican nuns.
Religious women who take vows to live a life of chastity, obedience, and poverty.
Nuns are solemnly professed religious sisters who live in a monastery, usually called an Abbey. Please note that Nuns are NOT Sisters. Sisters in the Catholic Church are religious women who take perpetual or simple promises, and usually live in a convent, teaching or nursing.
compare with mens was not compared with men ~they did many things -work - take care of the kids and family they did everything their families depend on them
Monks are male members of a religious community who typically live in a monastery, while nuns are female members who live in a convent. Monks often focus on contemplation and prayer, while nuns may have a broader range of activities including teaching, caring for the sick, and social work. Both monks and nuns take vows of poverty, chastity, and obedience.
