Editing Genuflection (section)

====Tridentine Mass====
In the [[Tridentine Mass]] this genuflection is made on any day on which the Creed is recited at Mass, as well as at several other points:
* at the words ''et Verbum caro factum est'' ("and the Word became flesh")<ref>{{bibleverse||John|1:1-14}}</ref> in the prologue of the Gospel of John, which is the usual [[Last Gospel]], as well as the Gospel for the third Mass on Christmas.
* at the words ''et procidentes adoraverunt eum'' ("and falling down they adored him") in the Gospel for the Epiphany, Matthew 2:1-12 (which before 1960 was also the Last Gospel of the third Mass on Christmas)
* at the words ''Adiuva nos ...'' during the (identical) Tract said on Mondays, Wednesdays, and Fridays in [[Lent]], except on Ember Wednesday. But no genuflection is envisaged when after Septuagesima the same Tract is used in the votive Mass at a time of Mortality (''Missa votiva tempore mortalitatis'')
* at the words ''et procidens adoravit eum'' ("and falling down he adored him") at the end of the Gospel for Wednesday in the Fourth Week of Lent, John 9:1-38
* at the words ''ut in nomine Iesu omne genu flectatur caelestium, terrestrium et infernorum'' ("that in the name of Jesus every knee should bow of those that are in heaven, on earth, and under the earth") in the Epistle ({{bibleverse||Philippians|2:5-11}}) of Palm Sunday, the Feast of the Exaltation of the Holy Cross on 14 September (and also, before 1960, the Feast of the Invention of the Holy Cross on 3 May) and in the Epistle ({{bibleverse||Philippians|2:8-11}}) of the votive Mass of the Passion of the Lord.
* at the words ''[[Veni Sancte Spiritus|Veni, sancte Spiritus]]'' in the Alleluia before the Sequence on Pentecost Sunday and the Octave of Pentecost and in the votive Mass of the Holy Spirit

In the [[Maronite Catholic Church]], there is an evocative ceremony of genuflection on the feast of [[Pentecost]]. The congregation genuflects first on the left knee to [[God the Father]], then on the right knee to [[God the Son]], and finally on both knees to [[Holy Spirit|God the Holy Spirit]].
