Which is better: to pray to Jesus or to the holy Spirit?
During our prayer meetings, we almost always pray to Jesus, rarely to the Holy Sprit. I am told they are the same.
But, the three divine Persons are distinct. From creation to the birth of Christ, it was the Father's era. Then came Jesus Christ's era. Today, with the Charismatic Renewal, we must be in the era of the Holy Spirit.
Therefore, should we not require more prayers to the Holy Spirit?
There is no place for jealousy in Heaven. "When we talk to God in prayer, we do not separate His Son from Him" (Saint Augustine).
Through liturgy, the Church invites us to address the Father or the Son or the Holy Spirit or all the three together.
"Blessed are you, Almighty Father!
Blessed are you, Beloved Son of the Father!
Blessed are you, Spirit of the Father and the Son!
Blessed are you, the One, the Holy One!"
(Feast of Holy Trinity).
With regard to assigning one period of human history to one particular Person, that must be done with discretion, keeping in mind that there is only one God. All of the "ad extra" (external) works of God concern the three Persons.
The tendency to over-distinguish may lead to difficulties as were experienced in the past. This was for example one of the problems encountered by Joachim of Flora, an Italian monk who died in 1202.
It does not matter whether a prayer is addressed to the Father, the Son or the Holy Spirit; it goes up to God and that is perfect! Let us not forget any of the Persons of the Holy Trinity.
