Luke 1:68-79 is NOT the Gospel - it is a canticle serving as a Responsorial Psalm (or Psalm for short).
The Gospel is what is known in some denominations as a Lesson. The canticle is not a Lesson - it is a response, frequently sung, to a Lesson.
It also appears from the CCT website that the terminology "second lesson" is used rather than "New Testament". Since I don't have the source document from the CCT - only denominational RCL documents, I may be wrong on this.
