Saint Thomas Aquinas (1225 – 7 March 1274), was a Doctor of the Church, Philosopher, Theologian, Jurist, Dominican Friar, and Priest. Known as Doctor Angelicus "Angelic Doctor," and the Doctor Communis "Universal Doctor" his writings serve as a defense and proof of the validity of Christ's authority over all. The Summa contra Gentiles (also known as Liber de veritate catholicae fidei contra errores infidelium, "Book on the truth of the Catholic faith against the errors of the unbelievers"). The Summa contra Gentiles consists of four books. The structure of Saint Thomas's work is designed to proceed from general philosophical arguments for monotheism, to which Muslims and Jews are likely to consent even within their own respective religious traditions, before progressing to the discussion of specifically Christian doctrine.
Book I begins with general questions of truth and natural reason, and from chapter 10 investigates the concept of a monotheistic God. Chapters 10 to 13 are concerned with the existence of God, followed by a detailed investigation of God's properties (chapters 14 to 102). When demonstrating a Truth about God which can be known through reason, St. Thomas gives multiple arguments, each proving the same Truth in a different way.

Summa Contra Gentiles Book I: Divine Will Doesn’t Remove Chance or Enforce Necessity on Things
From Contemplating History
The Life of Arthur Plantagenet, Viscount Lisle | Henry VIII’s Forgotten Uncle, Edward IV’s Other Son
From History Calling
He was HENRY VIII’S FORGOTTEN UNCLE, the brother of the Princes in the Tower, Edward IV’s other son and Elizabeth of York’s other brother, yet the life of Arthur Plantagenet, Viscount Lisle, like so many illegitimate royal children, is shrouded in mystery. In this Plantagenet documentary from History Calling I’m going to look at what we do know about his life, from his mysterious origins (his mother may have been Elizabeth Lucy, mistress of Edward IV), to the early mentions of him in the sources which suggest he was raised alongside his legitimate siblings, the other children of Edward IV by Elizabeth Woodville, what happened to him after the disappearance of his brothers, Edward V and Richard of Shrewsbury, Duke of York and during the reign of his uncle, Richard III and how he ended up in the household of his half-sister, Queen Elizabeth of York. I’ll then discuss his life during the reign of Henry VII, who was his brother-in-law and his relationship with his half-nephew, Henry VIII, who at first showered him with favours, only to eventually have him imprisoned in the Tower of London. What happened to Arthur Plantagenet, Viscount Lisle after that is shocking and you won’t believe how he ultimately died. I’ll also tell you about his two marriages to Elizabeth Grey Dudley and Honor Grenville Basset and children, his work as the deputy of Calais in France and how he was responsible for feeding the pregnant Jane Seymour’s cravings for quails.
Sit back and enjoy what I hope will be the best royal history documentary on Arthur Plantagenet you’ve ever seen!
The Miraculous Vision Behind the Feast of Corpus Christi
Until Bugini's "reforms" of 1955, today would hve been the Saturday Within the Octave of Corpus Christi. Restore the stolen Octaves!
By Philip Kosloski
The celebration of Corpus Christi can be traced to a vision that a 13th-century Belgian nun named Juliana had of the liturgical year.The Roman Rite of the Catholic Church celebrates the feast of Corpus Christi (translated into English as the "Body and Blood of the Lord") each year after Trinity Sunday.
It's become a staple of Roman Catholic devotion and highlights the Real Presence of Jesus in the Holy Eucharist.
However, the Church did not always celebrate this feast, and a large influence behind it was a a 13th-century Belgian nun named Juliana.
St. Juliana's vision
Juliana was deeply devoted to the Holy Eucharist from an early age and according to Aleteia writer Joanne McPortland, "entered religious life at the age of 13, serving in a hospice for lepers run by her community."
It was during this time that she began to have a peculiar vision. Author Heinrich Stieglitz narrates the vision in his book The Church Year: Talks to Children:
As early as her sixteenth year Juliana had a remarkable vision while she was at prayer. She saw the full moon shining brightly, but upon it was a dark spot as if a piece of it were broken out. At first she could not understand the vision. The oftener she looked at this strange sight, the more her wonder grew.
Initially she thought the vision was demonic in origin and begged God for help:
"Is it a temptation of the Evil One?" she asked anxiously. She prayed earnestly and yet the vision remained. Amid burning tears the girl asked her loving Savior to please explain to her what it meant.
According to the account, Jesus responded to Juliana's request and told her exactly what the vision was supposed to represent:
Finally Jesus told her, "The moon represents the ecclesiastical year. The dark spot within its shining surface means that there is still one feast missing. It is My will that a great festival be instituted in honor of My Sacred Body. Holy Thursday is more a day of sorrow than of joy. Now go and announce it to the world." The humble nun shrank from such a task and told our Lord so, "Lord," she said, "I am only a simple maiden and I am not at all worthy. So please entrust this work to holy and learned priests."
Initially Juliana didn't tell anyone, but over time she confided her vision to a few people and then the account made its way to the pope himself.
While St. Thomas Aquinas would eventually write beautiful poetic hymns for this new feast, the celebration would likely not exist if it weren't for the holiness of St. Juliana and her openness to receive God's word.

Why Medieval Blanket Systems Worked At -40° While Your $300 Bedding Fails
From Medieval Way
Medieval blanket systems, surprisingly effective even at -40°F, are explored alongside modern bedding. The video analyses the science behind both, revealing the surprising physics and materials of each. Discover why your expensive bedding might fail, and how ancient knowledge can improve your sleep.
It's 3:00 AM. A blizzard hits and the power goes out. Outside, it's minus 40 degrees Fahrenheit. Within three hours, your bedroom drops to 30 degrees. You're buried under three layers of blankets. You paid $300 for that memory foam mattress and another $200 for a weighted comforter. Yet you're shivering. Your expensive mattress feels like a block of ice against your back. You're sweating and freezing at the same time.
Now imagine a medieval peasant in 1315. No electricity. No central heating. Outside temperature? Same minus 40. His bedroom, if you can call it that, is a drafty stone hall with gaps in the walls. Yet he's sleeping soundly under a pile of straw and wool. He'll wake up warm. You'll wake up hypothermic.
What did a medieval farmer with literal garbage know that your $500 bedding system doesn't?

Why St Norbert Was Called Apostle of the Blessed Sacrament
Today is the Feast of St Norbert, founder of the Order of Canons Regular of Prémontré (Norbertines), who are dedicated to Eucharistic worship.
From Aleteia
By Philip Kosloski
St. Norbert possessed an intimate love of Jesus in the Holy Eucharist and he tried to ensure that his followers remained rooted in the Blessed Sacrament.St. Norbert founded the Canons Regular of Prémontré (commonly called the "Norbertines") in 1120, and from the very beginning he wanted his followers to devote themselves to both private and public devotion to the Blessed Sacrament.
This desire flowed out of his own deep devotion to Jesus' presence in the Holy Eucharist.
Apostle of the Blessed Sacrament
Writer Cornelius James Kirkfleet provides a few details about St. Norbert's devotion in his book History of Saint Norbert:
He himself never undertook any important work without first offering up the holy sacrifice of the Mass and spending hours in prayer prostrate before the altar. The very first chapter of the Constitution of the Order has for its title De tremendo altaris Sacramento and explains how to derive from the Blessed Eucharist true zeal for the salvation of souls.
One of the primary aims of the Norbertine Order is "To spread and increase devotion to the Blessed Sacrament."
Pope Francis recognized this essential part of the Norbertines in an address he gave to the religious order in 2022:
Following in the footsteps of Saint Norbert, the piety of the Premonstratensians reserves an increasingly central place for the Eucharist, both in the solemn and intimate community celebration, and in silent worship. Precisely as he is present for us in the Sacrament, so the Lord wants to be present through us in the life of those we meet.
Restoring faith
St. Norbert is also known for his defense of the Holy Eucharist, in particular when the city of Antwerp called upon his help. At the time there was a heretical preacher who tried to eradicate the city's devotion to the Eucharist. St. Norbert then took it upon himself to evangelize the city and restore the faithful's understanding of the Blessed Sacrament.
He was successful in his endeavors and the local people proclaimed him the "Apostle of the Blessed Sacrament," for his work in restoring their faith and devotion.
This is one of the reasons why St. Norbert is traditionally depicted holding a monstrance, highlighting the deep devotion he had to Jesus in the Blessed Sacrament and his missionary zeal in proclaiming belief in the Real Presence of Jesus Christ in the Eucharist.
St. Norbert's legacy continues to be passed on today by many Norbertines across the world, putting an emphasis on Eucharistic worship.
