Incorrect. With regard to the Priesthood, both religious and diocesan and as the dictionary confirms, celibacy and chastity are synonymous.
Main Entry: cel·i·ba·cy
Pronunciation: 'se-l&-b&-sE
Function: noun
1 : the state of not being married
2 a : abstention from sexual intercourse b : abstention by vow from marriage
Every person not married is called to "abstain". Period. Celibacy is the state of not being married and all those not being married are called to be chaste. Married couples are called to be chaste...they are not called to abstain from sex simply because they are married. Small nuance...but I think one that is important.
