Dressed in a black suit and tie, Fin delivered a poignant moment by reciting a bible verse, Proverbs 16:8.

"Hello, my name is Fin Affleck," they addressed the gathered attendees before proceeding to read the scripture.

This public appearance marks a significant moment for Fin, who was spotted with a bright pink buzzcut in February during a family outing. Additionally, glimpses of the new name were seen when Fin was photographed wearing a backpack embroidered with "Fin" during the same outing, as reported by OK Magazine.

The memorial service was held in remembrance of Fin's grandfather, William Garner, who died at the age of 85 on March 30. Jennifer Garner took to Instagram to share a heartfelt tribute to her father, expressing gratitude for his gentle demeanor and loving legacy.

"We were with him, singing Amazing Grace as he left us (did we carry him across or scare him away— valid question)," Jennifer wrote in the post. "While there is no tragedy in the death of an 85-year-old man who lived a healthy, wonderful life, I know grief is unavoidable, waiting around unexpected corners."

"Today is for gratitude," the actress continued. "We are grateful for Dad’s gentle demeanor and quiet strength," she noted. "For how he teased with a mischievous smile, and for the way he invented the role of all in, ever patient girl dad."

"There is so much to say about my dad — my sisters and I will never be done talking about how wonderful he was, so bear with us," she added. "But for today I share these memories with my appreciation for the kind and brilliant man, father, and grandfather he was, as well as the loving legacy he left behind."

Ben Affleck and Jennifer Lopez's blended family journey 

Jennifer Garner and Ben Affleck, who divorced in 2018 after a decade of marriage, have been co-parenting Fin and their two other children, Violet and Samuel. Since their divorce, Ben has rekindled his romance with Jennifer Lopez, with whom he tied the knot in 2021.

Emme Muniz, Lopez's daughter from a previous relationship, shares a sibling bond with Fin. Both Emme and Fin use they/them pronouns, as publicly announced by Lopez during a performance at the Blue Diamond Gala in June 2022.

"[The last time] we performed together was in a big stadium like this, and I ask them to sing with me all the time but they won't. So, this is a very special occasion, because they're very, very busy and booked and pricey," Lopez said at the time.

"They cost me when they come out, but they're worth every single penny because they're my favorite duet partner of all time," the singer continued.

Lopez has said that when the children between the couple "moved in together," it was a "dream come true," but also an "emotional transition."

"And it's just been a phenomenal year," Lopez said in January on Today. "Like, my best year I think since my kids were born."
