"Holy Orders is the sacrament through which the mission entrusted by Christ to his apostles continues to be exercised in the Church until the end of time: thus it is the sacrament of apostolic ministry. It includes three degree: episcopate, presbyterate, and diaconate." -Catechism of the Catholic Church, 1536

The first step any man should take if he is hearing the Lord call him to priesthood is talk to his parish priest. Start by reaching out to Fr. Francis.
