The Evangelical Law is another name for the Law of the Gospel or the New Law.
From the Glossary appended to the
Catechism of the Catholic Church:
GOSPEL, LAW OF THE: The New Law, prepared for by the Old Law in the time of the Old Covenant, is the perfection here on earth of the divine law, natural and revealed. It is the work of Christ, expressed particularly in the Sermon on the Mount, and of the Holy Spirit, by whose grace it becomes for us the interior law of charity. (1965)
It is further discussed in the
Catechism of the Catholic Church, in the section on “The New Law or the Law of the Gospel,” paragraphs
1965-1975,
1983-1986.
St Thomas Aquinas discusses it as the New Law in his
Summa Theologica, First Part of the Second Part, questions
106,
107,
108.
The Evangelical Law includes the commandments and precepts of Christ (love one another, etc.), the evangelical counsels of Christ (poverty, chastity, and obedience), and seven sacraments of Christ.
